1.3 Exercise 12

Avg difficulty 2.5

Unless otherwise specified, for problems 1 through 10, the indices of refraction of glass and water should be taken to be 1.50 and 1.333, respectively.

The path of a light beam in air goes from an angle of incidence of 35°35 ° to an angle of refraction of 22°22 ° when it enters a rectangular block of plastic. What is the index of refraction of the plastic?
