Question

two plane mirrors are inclined at an angle x. A ray of light is incident at angle of incidence i. the ray is reflected from this mirror, falls on the second mirror from where it is reflected parallel to the first mirror. what is the value of i, the angle of incidence in terms x?

Answer 1

Two plane mirrors are inclined to one another at an angle 50°. A ray is incident on mirror M1 at an angle i as shown in the fig. The reflected ray from mirror M2 is parallel to mirror M1. The angle of incidence i is
