Problem
Two plane mirrors are inclined to each other with their reflecting faces making acute angle. A light ray is incident on one plane mirror. The total deviation after two successive reflections is:
(1) independent of the initial angle of incidence
(2) independent of the angle between the mirrors
(3) dependent on the initial angle of incidence
(4) dependent on the angle between the mirrors.
