Question

If the angle between two Plane mirrors is 120⁰ then Calculate the numbers of images found?​

Answer 1

Answer:

Therefore number of image form when 2 mirrors are kept at 120° is 2

Explanation:

The formula to find the number of images is

N=( 360/tita)-1

So we are given

Tita = 120°

N=( 360/120)-1

= 3–1= 2

Therefore number of image form when 2 mirrors are kept at 120° is 2
