Chapter 1 Refraction of Light 1. Reflection always occurs when a ray hits any surface such that: a. The incident [SI] ray and the reflected ray [IR) lie on the same side with respect to the surface. b. The incident ray [SI] and the reflected ray [IR) lie on opposite sides with respect to the Normal (NI). c. The angle of incidence (i) is always equal to the angle of reflection (r). R R N N Reflected ray Reflected ray Normal (Perpendicular to the surface at the

Light that takes a path from point A to point B will take the same reverse path in going from point B to point A, even if reflection or refraction is involved. So if you can’t see the driver, the driver can’t see you. 13. In spearing a fish with a spear, you should aim below the apparent position of the fish to account for the refraction of the light that you see coming from

This experiment seeks to demonstrate the law of reflection - the angle of incidence is equal to the angle of reflection when measured from the normal. Equipment Single slit raybox with power supply Paper Ruler Protractor Sharp Pencil Plane mirror Support for mirror (e.g. wooden block with a groove in, or plasticine) Method Draw a line on the paper. Place the mirror on the line and support it so it does not move. Shine the beam from the raybox towards the mirror. Use the pencil

incidence compares with the angle of reflection by always sharing the exact same measurement. For each trial performed, the incident ray would be directed towards the mirror and the reflected ray would match the incidence ray but would reflect the other way. For example, when trial 1 was performed and the angle of incidence was aimed on the plane mirror, its angle equaled 45°. The angle reflected off the mirror in the same angle which also equaled 45°. This reflection came off a smooth surface which was

compare with the angle of reflection? B. In trial 5, you aimed the incident ray directly along the normal. Describe the path of the incident and reflected rays for this special case. C. Where might errors occur in this activity? D. How would these errors affect your conclusion? E. Billiards is a game that makes use of reflection (Figure 2). How could the results of this activity help you in such a game? F. What other sports or activities make use of the reflection rule that you discovered

There are four different ways to identify public opinion on different issues: election results, polls, media, and interest groups. Each effects how a certain issues can be viewed on popularity. For example, election results shows how a group of people can vote a certain way to make what they want happen. However, due to the electoral college in our country, the person voted in is not necessarily what the people want. A candidate could win a larger state which had a larger amount of electoral votes

Christian Llerena BUS 200 Dr. Lasher 3/19/12 The Electoral College is defined as “a body of electors chosen by the voters of each state to elect the President and Vice President of the United States”. The Electoral College system has been a staple in the United States since the ratification of The Constitution, however there is much debate on whether it should remain or be done away with completely. In this essay, I will give a brief history on the Electoral College, how it works, and why

gives wrong election date in Spanish voter cards” The Arizona Democratic Party is calling for a meeting with the Maricopa County Recorder following an error in relationship with the approaching election, the Maricopa County’s elections office says that they mailed out just about 2 million new voter registration cards, and that only about 50 of the cards, apparently handed out at the receptions of their offices had an error. The mistake in the voter cards was that the incorrect election date was
