Homework Statement
A light ray in air is incident on a glass plate whose index of refraction is 1.42. The angle of refraction (transmitted angle) is one-half the angle of reflection. (Take the index of refraction in air to = 1.00).
A) Relative to the normal to the plate’s surface, what direction does the ray entering the glass bend?
a. toward the normal b. away from the normal c. neither
B) How is the reflected angle related to the incident angle?
a. 2 x the incident angle b. unrelated c. equal to the incident angle
C) What is the angle of refraction?
a. 37 b. 41 c. 45
