Question

if 2 mirrors are inclined at a angle of 1200 to each other,how many images will be formed between them​

Answer 1

Answer:

2

Explanation:

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:

2 image

Explanation:

by using the formula of image formation

that is n=(360/angle)-1

so,(360/120)-1

3-1=2
