1. Red light travels at 2.07×108 m/s in a particular type of oil. What is the index of refraction for red light in the oil?
2. A beam of light travels from a medium with an index of refraction of 1.21 to a medium with an index of refraction of 1.46. If the incoming beam makes an angle of 14.0° with the normal, at what angle from the normal will it refract.
