Question

Two plane mirrors are inclined to each other such that a ray of light incident on the first mirror M 1 and parallel to the second mirror ( M 2 ) is finally reflected from the second mirror ( M 2 ) and parallel to the first mirror M 1 . The angle between the two mirrors will be:

As given in question A B | | C O ∴ ∠ A B F = θ From laws of reflection ∠ O B C = θ Similarly C D ‖ O B ∴ ∠ D C E = θ Again from laws of reflection, ∠ O C B = θ ∴ 3 θ = 180 o ⇒ θ = 60 o
