1. Define index of refraction.
2. Is it possible for an index of refraction to be less than one? Why or why not?
3. Consider a light beam hitting a block of plexiglas (index = 1.6). It hits at an angle of 25 degrees, with respect to a normal line at the surface. Find the angle of refraction inside the material.
4. A light ray hits the side of an equilateral prism on its left side, striking it at an angle of 30 degrees with respect to a normal line. If it refracts at an angle of 20 degrees inside the prism, what is the index of refraction of the prism? Also, draw an diagram that represents this problem.
5. What is a critical angle of refraction?
