Pamela Perez Abstract The purpose of this experiment was to observe and measure the reflection, refraction, and dispersion of light through mirrors, lenses, and prisms. The experiment involved the interactive use of light to measure quantities that could be used to find properties of the given materials. The results of our experiment yielded focal lengths of 56mm for a concave mirror and 76mm for a convex mirror as well as an index of refraction of acrylic plastic equal to 1.46, and 1.39 with a

Final examination Theory 1. Explain the dispersion of light by a transparent dielectric material. The phenomen of dispersion is connected to the fact that the refractive index is dependent on the wavelength. Due to dispersion, the light waves from a complex radiation are bent by different angles as they enter a dispersive medium and they may be visualized separately. The index of refraction of a transparent dielectric medium is defined as the ratio of the speed of an electromagnetic wave

converging lenses; nearsightedness can be corrected with diverging lenses ../ The total internal reflection is the complete reflection that takes place within a substance when the angle of incidence of light striking the surface boundary is greater than the critical angle ../ The critical angle is the angle of incidence at which the refracted light makes an angle of 90° with the normal ./ Total internal reflection occurs only when the light moves from a medium with higher index of reaction to one medium

Refraction, Reflection and Optics ITT Technical Institute Physical Networking – NT1310 11/10/2014 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

Crosstalk- unwanted transfer of signals between communication channels. Waveguides- a metal tube or other device confining and conveying microwaves. FTTH- Fiber to the home (FTTH) is the delivery of a communications signal over optical fiber from the operator's switching equipment all the way to a home or business, thereby replacing existing copper infrastructure such as telephone wires and coaxial cable. Simplex- Simplex refers to one-way communications where one party is the transmitter

experiment is to study the laws of reflection, refraction, and total internal reflection; to measure the focal lengths of the mirrors with convex and concave surfaces; and to measure the index of refraction of water. Theory: If a ray of light is incident on a flat surface: the angle of incidence a is the angle that the incident ray makes with respect to the normal, which is a line drawn perpendicular to the surface at the point of incidence. The angle of reflection r is the angle that the reflected

“Glory” & “Paths of Glory” Film History Justice Dominique October 7, 2014 In "Paths of Glory" war is observed in positions of command. This film about an accurate affair in World War I mingles the idea that status differentiations are more significant than nationwide differences with the way soldiers were viewed or treated as dispensable in combat of war, the philosophy that soldiers are simply ragdolls in the paws of generals who put on a production of what war is if it were just

Glory Assignment- Theme Glory was a 1989 film based on the 54th Massachusetts Volunteer Regiment. The theme of “Glory” shows the fight of those blacks known as the “Fighting Fifty-Four”. These African Americans were kept from fighting in the Civil War due to discrimination and racism. During War, Captain Shaw is hurt in the Battle of Antietam and sent home to Boston. He visits his family there and meets the abolitionist Frederick Douglass, a previous slave. Shaw is offered a chance to be ranked

The movie Glory tells the story of the forming of the 54th Regiment of the Massachusetts Volunteer Infantry, which was constructed entirely of African American soldiers and commanded by Colonel Robert Gould Shaw. The regiment included different men of different backgrounds. Some of the soldiers were free men of the North, some were escaped slaves, and some were even businessmen. The 54th, as it was referred to, was a prime example and proof that was contrary to the belief that black men were unfit

“Where Death and Glory Meet: Colonel Robert Gould Shaw and the 54th Massachusetts Infantry” by Russell Duncan was the third and final informational text for my research on the historical 54th Massachusetts regiment. This text being another biography of Robert Gould Shaw, the author paints the image of a spirited leader that garnered unexpected national attention because of his story's’ context. He is one of the first White-American military commanders leading a platoon of Black-Americans. Shaw is
