Question

# When the angle between two plane mirrors is $$60^o$$, how many multiple images will be formed by the mirrors?

A
5
B
6
C
7
D
8

Solution

## The correct option is A $$5$$Number of images formed by two plane mirrors at an angle of $$\theta$$is given by$$no. of images = \dfrac{360}{\theta}-1$$According to question$$\theta=60^{0}$$Hence $$no of images=\dfrac{360}{60}-1$$$$no. of images=5$$Physics
