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 $$(M_2)$$ parallel to the first mirror $$(M_1)$$. The angle between the two mirrors will be :

A
90o
B
45o
C
75o
D
60o

Solution

## The correct option is C $$60^o$$Assuming angles between two mirrors be $$\theta$$ as per geometry, sum of angles of $$\Delta$$$$\lambda1+\lambda2=360-20=180+\theta$$$$3 \theta = 180^o$$$$\theta = 60^o$$Physics
