Question

what happens when two mirrors are inclinef to each other?​

Answer 1

Answer:

if we take the angle of inclination between the two mirrors as θ, then the angle which the incident ray makes with the mirror (M1) is θ. Similarly we are given that the final reflected ray from the mirror (M2) is parallel to the mirror (M1). So we get the angle that the reflected ray makes with the mirror (M2)is θ.
