A light ray traveling through a material with an index of refraction of n1 is incident on a material with an index of refraction of n2. What is the critical angle for this boundary (4 points)? c. What is the speed of light as it travels through the material with the index of n2 (3 points)? 3. Assign values to n1 = 1.5 and n2 = 1.3 (note that n1 should be larger than n2)
