Show all the solutions. Round off final answers up to two
decimal places. (3 points for each question).
1. The index of refraction of diamond is 2.42. Find the speed of
light in diamond.
2. A ray of light traveling through air (n = 1) is incident upon
a flint glass (n = 1.66). The angle of refraction formed is 33
degrees. What is the angle of incidence?
3. A ray of light in air (n = 1) is incident 55 degrees with the
surface of ethyl alcohol (n = 1.36).
a) What is the angle of reflection?
b) What is the angle of refraction?
4. A prism (n = 1.5) is connected to a device in such
a way that light comes from it. The prism is placed in water (n =
1.33).
a) What is the critical angle when light travels from the
prism to the water?
b) Given with an angle of incidence of 50 degrees,
does total internal reflection occur? Support your answer.
