Question

if two mirrors inclined at an angle of 120 degree and object is placed at 60 degree from either mirror . how many numbers of images would be formed​

Answer 1

The formula to find number of image 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

Answer 2

Answer:

120⁰ is 2

hence, Tita = 120
