...Investigating Snell’s Law Research Question: The effect that the angle of incidence of white light has on the angle of refraction from one transparent medium to another. Introduction: Snell’s law state: When light passes from one transparent medium to another the rays of light refract (bend). Snell’s law (Law of Refraction) states that: n*=sinⅈsinr=n2n1=V1V2 for the purpose of this experiment we will be proving that: sinⅈsinr=n2n1 or n1sinⅈ=n2sinr where n1 and i are the index of refraction and angle with the normal to the surface for the incident ray, respectively, and n2 and r are for the refracted ray. Aim: The aim of this investigation is to prove determine the relative refractive index of perspects. Hypothesis: Sin i / Sin r will produce a constant ratio – the refractive index for perspects Variables: Independent Variable: Sine of the angle of incidence (Sin i) Dependent Variable: Sine of the angle of refraction (Sin r)\ Controlled Variables: The light source was kept constant, the same block of perspects was used. Uncontrolled Variables: Not relevant Apparatus: * Ruler, Protractor, Incandescent Light Source Procedure: Given on the assignment sheet (Investigating Refraction: Snell’s Law) Results: Raw Data | Processed Data | Trial # | Angle of Incidence (°) | Angle of Refraction (°) | Sin i | Sin r | Sin i/Sin r | 1 | 53 | 33 | 0.798 | 0.546 | 1.462 | 2 | 41 | 27 | 0.656 | 0.454 | 1.445 | 3 | 31 | 21 | 0.515 | 0.358 | 1.439 | ...

...It’s a rainy day today! I am sitting at my window and watching the beauty of nature. This is great sight! I love the scenes the nature has created today. Let me share it with you! The falling water droplets make the air cool and environment calm. When it starts raining slowly every one rushes to safe place to save them. Women rush to roof to take their cloth down to save from getting wet. Small children gets excited. You can easily see them jumping and trying to come out to take a feel of rain. Have you watched the scene on roads when it starts raining. … ha ha its funny scene. Some people try to escape by running/ some try to take shelter under other’s roof / some take bag or books magazines on their head and try to escape. But this is all when it is weak rain. … but when it is heavy rain one has no way. Even umbrellas are insufficient. The heavy lightning with thunderous sound….. God save us! Prays the poor in his hut. Every one comes out on window and peeps out side scene. If you have a field in front you will hear songs of frog. Have u seen them when they speak/ their vocal sac. This seems like a baloon. The old ponders the rain scene and remembers his child hood and young days. He never forgets to guard his grand children waiting to jump in rain. Still u see the eager ness of children if they could have been permitted to take a bath. What is more that when it rains with heavy wind. U shut your door and window. And still manage to peep out side! …Ha ha...

...William Wordsworth's piece, "The Rainbow," offers an intriguing look into the human soul. Standing at only ten lines, the poem details a journey through Wordsworth's philosophical beliefs. Although it appears simplistic, this poem details many complex ideas. Wordsworth's opening lines explain how: "My heart leaps up when I behold / A rainbow in the sky" (1-2). Wordsworth is overjoyed at nature, a common theme in all of his work, but what's more is that he states: "So was it when my life began; / So it is now I am a man; / So be it when I shall grow old, / Or let me die!" (3-6). As a child, ("when my life began") Wordsworth felt the same way about rainbows and nature as he does now, completely awestruck and in reverence. Moreover, Wordsworth hopes his adoration of nature will continue as he matures, even to his death bed. If not, Wordsworth would rather die prematurely. The last three lines contain one of Wordsworth's most famous phrases: "The Child is father of the Man; / And I could wish my days to be / Bound each to each by natural piety" (7-10). Wordsworth is happy enough to have kept his appreciation of nature and only wishes it will last him forever, in "natural piety." With the line: "The Child is father of the Man", Wordsworth evokes a number of ideas. To start, Wordsworth details how the child is father simply through greatness. The child falls in love with nature as soon as it is born. This admiration is both an inherent trait as well as something to be gained when...

...Rainbow (also known as Ritchie Blackmore's Rainbow or Blackmore's Rainbow) were an English hard rock band formed in California, controlled by guitarist Ritchie Blackmore from 1975 to 1984 and 1994 to 1997. They were originally established with American blues rock band Elf's members, though over the years Rainbow went through many line-up changes with no two studio albums featuring the same line-up. In addition to lead singers Ronnie James Dio, Graham Bonnet, Joe Lynn Turner and Doogie White, the project consisted of numerous backing musicians. The band started out combining mystical lyric themes with neo-classical metal, but went in a more streamlined commercial style following Dio's departure from the group.[1] Rainbow were ranked No. 90 on VH1's 100 Greatest Artists of Hard Rock.[2] The band has sold over 28 million albums worldwide and 4 million albums in the United States.

...Unit 7. Assignment 1. Refraction, Reflection and Optics Refraction: The most common real life example used when discussing refraction is a straw in water. When a straw is placed in a glass of water and viewed from the side, it appears to be broken or bent. This is due to the difference in the refractive indices of air and water. Since water is denser than air, the straw appears to bend as the light it reflects is slowed by the density of the water. This phenomenon also makes submerged objects, such as fish look closer to the surface than they actually are. Another common example is a rainbow, where sunlight is refracted by raindrops. Sunlight consists of a mixture of different wavelengths, or colors, of light, with blue, for example, having a shorter wavelength than red. When this light passes through raindrops, the shorter wavelengths are bent more than the longer ones, splitting the light into its different colors. Reflection: Pretty much everything you see could be considered reflection. The fact we can see is due to light reflecting off of objects and into our eyes. A good example, I guess, is the moon. When it glows at night that is just light from the sun reflecting onto the Moon's surface, and bouncing back, giving it that glow. Degradation of signal strength in fiber-optic transmission. The main factors that affect this is number of connectors, splicing, Quality of Fiber / connectors, also not using an Attenuator according to the distance, or using dirty attenuators...

...phycisian that discovered the color spectrum used a glass prism to show us how it works. He darken up his room and opened a little whole and let the light come through it, there then he placed a glass prism and let the light hit it. As the light hit the prism rainbow colors appeared he then called it “color spectrum.” Isaac Newton was the first one to discover that colors come from a white color. Hypothesis We believe that as the light hits the glass it wont show as much of the colors of the rainbow. But it will show enough to the point where it helps us know that the white light does creat multicolors. Materials Materials needed for this experiment would be: * Dark room * A flash light * A glass prism * And a white board (for the colors could be seen) Procedure First you will need to turn of the lights in the room where you are at. As soon as it is dark you get the glass prism and the flashlight facing it to a white board. Once it is faced on the white board you placed the glass prism in front of the flashlight, then if you pay close attention you could see the colors of the rainbow appear in the white board. Conclusion Our hypothesis was right not all colors appeared but some of the rainbow colors appeared in the white board. Isaac Newton did a great job finding out that a white light can be created into...

...2.1. Scope Statement The Rainbow Paint Warehouse ensures proper removal, relocation, installation, and operation of all unit equipment from the old warehouse into the new warehouse. The relocation of the Rainbow Paint Warehouse is a big opportunity for our company to expand in the new market. The biggest challenge for us is to move the products from the old warehouse to new warehouse and make sure that fits in the redesign space according to the needs of the merchandise shelves. Some key factors to work into this project include the fact that the size of the warehouse is more than the old warehouse in Cedar Park. So we have to make sure that we order more products to completely fill our warehouse and to satisfy the big Austin market. Moving the products to a new warehouse the project team must also make the arrangements for the procurement of new performant lifting equipment (forklifts), insurance policy and security service. Human Resource department makes an important role in hiring and training the new employees and making sure that everything is done in a specified period of time. Completion of the project on time give the marketing department to finish their part of job before December so that they can contact the old customers with the new address and target our new customers. The most logical approach to our project given the requirement to maintain 100% uptime and with the limited budget will be to continue in three phases: * Prepare the new building with new equipment...

...credit I am going to talk about the sun and how different polarizer’s work. As I stated above rainbows can come in different forms; to elaborate on this topic I am going to talk about the different types of rainbows. There are primary rainbows, secondary rainbows, spurious rainbows, supernumerary rainbows, fogbows or white rainbows, and lunar rainbows. The main thing that is talked about between primary rainbows and secondary rainbows is that they can be reflected off each other. Simply put a secondary rainbow is a rainbow that is reflected twice of the drop. This means that instead of looking like a normal rainbow that has red, orange, yellow, green, blue, and violet respectively from the outside in. They are opposite which means that the colors are reversed. Some other the other rainbows are the spurious or supernumerary bows which is a mix of a primary and secondary rainbow. These rainbows are faint in color and are hard to see because they are a mix of a secondary and primary rainbow. Some of the special rainbows that are rarely seen by humans are the lunar rainbows because they are caused by the moonlight. With these rainbows the colors are different than regular rainbows because the light source is the moon. They appear as white and different shades of grey. Now before I start talking about why the sky is blue I want to first talk about each of the seven colors in the rainbow. I hope that this has cleared up any confusion that you had about this...

...9-508-111 REV: JUNE 24, 2009 ANITA ELBERSE JASON BERGSMAN Radiohead: Music at Your Own Price (B) From the moment Radiohead announced its “name-your-own-price” model for the release of its new album In Rainbows, there was wild speculation about how consumers would react. The first insights emerged from the research company comScore. Through a panel of around 2 million people worldwide who allowed their online behavior to be tracked, comScore observed nearly 1,000 visitors to the In Rainbows site. Based on those data, the company estimated that 1.2 million people had visited the site during the first 29 days of October. Using several hundred actual transactions that it had recorded, comScore estimated that two out of every five downloaders had paid for the album, leading to an average price of $6 across this group (see Table A). Table A Radiohead’s In Rainbows: Estimated Online Album Download Statistics U.S. Percent of People Who Paid for Download Percent of People Who Downloaded for Free Average Amount Spent per Paid Download Average Amount Spent per (Paid or Free) Download 40% 60% $8.05 $3.23 Non-U.S. 36% 64% $4.64 $1.68 Worldwide 38% 62% $6.00 $2.26 Source: comScore. Of those who downloaded the album, 62% paid nothing. However, 17% paid between $0.01 and $4.00; 6% paid between $4.01 and $8.00; 12% paid between $8.01 and $12.00; and 4% paid between $12.01 and $20 (with each group accounting for 8%, 12%, 52%, and 27% of the total revenues, respectively).

...Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind the observer at a low altitude angle. Because of this, rainbows are usually seen in the western sky during the morning and in the eastern sky during the early evening. The most spectacular rainbow displays happen when half the sky is still dark with raining clouds and the observer is at a spot with clear sky in the direction of the sun. The result is a luminous rainbow that contrasts with the darkened background. During such good visibility conditions, the larger but fainter secondary rainbow is often visible. It appears about 10° outside of the primary rainbow, with inverse order of colours. The rainbow effect is also commonly seen near waterfalls or fountains. In addition, the effect can be artificially created by dispersing water droplets into the air during a sunny day. Rarely, a moonbow, lunar rainbow or nighttime rainbow, can be seen on strongly moonlit nights. As human visual perception for colour is poor in low light, moonbows are often perceived to be white.[4] It is difficult to photograph the complete semicircle of a rainbow in one frame, as this would require an angle of view of 84°. For a 35 mm camera, a wide-angle lens with a focal length of 19 mm or less would be required. Now that powerful software for stitching several images into a panorama is available, images of the entire arc and even secondary arcs can be created fairly easily from a series of overlapping...

...Most people nowadays know that a rainbow is the reflection of light on water droplets but for centuries and centuries, all over the world people considered rainbows as magical, as a symbol of the gods. The way people see rainbows is still magical, the rainbow is often seen as a symbol for hope. Like English poet Lord Byron said “The way I see it, if you want the rainbow, you gotta put up with the rain.” (George Gordon “Lord” Byron.) Even if stories about rainbows are different around the world they all have some elements in common. Rainbows have always been an important topic in the mythology because rainbows have something "magical" and extraordinary. The most famous rainbow myths come straight from Europe. In the Norse mythology the rainbow...

...9-1-2011 5th Period English Myth/Legend Writing How did the rainbow appear? A long time ago, in a far away land in South America there was a small town called Carthage, people not really the wealthy end of the town. All of a sudden people started becoming wealthier, entering the woods, being in there for hours, and coming out with money as they referred to as “Gold”. It’s very bizarre how out of the random this decides to happen. It all started when a young girl named Penelope entered the forest on the West side of Carthage. She kept saying she saw a little person. He was very short, less than 4 feet, who was always wearing green, pointy shoes, a green hat with a tad bit of yellow on it. Every time it would rain she’d see this man appear. One day after school, after days of envisioning this man, who he was, where he came from. The ultimate question was why it is when he goes in the forest; he comes out with this thing called “Gold”. This happens to be very very valuable. The people, who were poor, began to become rich and wealthy. As Penelope waited patiently for the bell to ring for her to begin her journey .She kept wondering about what she would spend her gold on. The bell just rung, Penelope was the first one out of the class room. It was raining outside, so Penelope waited inside until it stopped raining. As she waited she saw the little man standing outside near the forest. She yelled “Excuse me!” he looked at her and ran. She kept yelling “wait! Wait! Please!” nothing...

...The Girl The girl in the black rain coat sat calmly on the newly finished bench waiting for the bus. It was a gray cement bench, with writing on the top, like a tombstone, definitely dedicated to someone whose name she couldn’t quite read. It didn’t matter anyway. It was raining hard enough to see the rain come straight down like elongated bullets. The bus arrived in the rain, spewing water on both sides. The girl in the black rain coat sauntered up the stairs of the Tri City Transit Bus, paid her fare, and found an empty seat on the crowded bus. Despite the rain coat’s unflattering bagginess, it wasn’t hard to tell she was a beautiful woman, drop dead gorgeous by anyone’s standards. Long hair black as a dahlia framed an innocent untanned complexion. The next stop came and its only passenger was quick to notice the girl in the black raincoat’s unusual beauty. Spotting lips as red as her cherry red boots, he approached her seat. Thrown off balance by her beauty, he awkwardly asked, “Excuse me, is anyone sitting here?” “No, feel free.” So he sat down next to her. More caught his eye. He saw a single drop of water running down her face. Or was it a tear, he thought. Noticing her eyes were shiny and wet, he believed he found an opening. “What’s a girl as pretty as you got to cry about?” He asked. She solemnly looked at him. “My boyfriend died, I’m heading to his funeral.” “I’m really sorry for you. Let me know if there’s anything I can do. I’m Joseph...

...The story that I like the most is “Big Bill”. The personality of each character, either the main or minor characters, is totally different and that made the story pretty interesting. The theme “friendship” made it even more appealing to me. Therefore, I had chosen this story to be the one that I will be writing about in this essay. The main character of this story is Tulsi Babu. He is different from most ordinary beings, as he is not surprised by almost everything. He thinks that “everything” has a reason behind it. This part in the story would convince you in that, “‘Tulsi Babu went back to his desk. ‘I can’t see what’s so special about a double rainbow. Even there were twenty rainbows in the sky, there would be nothing surprising about that. Why, one can just as well go and stare at the double-spired church in Lower Circular Road!’” Sometimes, he will add a little sense of humour that will make his words interesting. Tulsi is a part-time herbalist and an upper division clerk of Arbuthnot & Co Company. He is scrupulous in his work and the sentence “Baba gave adequate directions which Tulsi Babu noted down carefully.” tells us so. Not only is he hardworking, he also treats, Bill, his “ex-pet” very good. He gave Bill the best when it was in his house and he was really sad while saying goodbye to Bill the last time. He even lost his appetite when he sent Bill back where it had came from, although you cannot see from his facial expression. He is also very thoughtful towards...
