Question

State the number of images of an object placed between the two plane mirrors, formed in each case when the mirrors are inclined to each other at (i) 30⁰ (ii) 180⁰​

Answer 1

Explanation:

Angle between the mirrors, θ = 30

Now,

n

= 360/θ

360/30

= 12

Angle between the mirrors, θ =180

NOW n = 360/ θ

n=360/180

n= 2
