Question

When a ray of light changes media , it will refract (bend). With angles being measured from the normal, the amount of refraction can be found using Snell's Law . Traveling through any medium light will have a speed given by the equation shown where n represents the index of refraction and is the speed of light in a vacuum (3 * 10 ^ 8 * m/c) .

A) In the picture  of refraction shown which index of refraction is larger n1 or n2

B)In what medium does the lightbeam shown travel faster

C) Measure the angles, Assuming n1 refers to vaccum what is the value of n2? How fast does light travel within n2?
