Snell's Law homework

1. Review the derivation.

2. Solve these problems:

A. What is the index of refraction for a material in which light is slowed to half its speed in a vacuum?

B. Water has an index of refraction of 1.33. What is the speed of light in water? (Water you waiting for?)

C. Light passes from air to a piece of plastic, with an initial angle of 50 degrees and refracted angle of 30 degrees. What is the index of refraction of this plastic?

D, A material has an index of refraction of 1.7. Light is refracted at an angle of 44 degrees inside the material. What was the original angle outside the material?

  1. In 2 A, did you mean index of refraction? It says retraction.
