Question

when a object is placed between two parallel mirrors then the number of images formed

Answer 1

The formula to find Number of images (n) formed between two plane mirrors inclined at angle, θ between them is as follows:

Number of images formed (n) =

$\frac{360}{θ} - 1$

Substituting the different values of angles between two inclined mirrors we can tabulate the answer as given in table:

Angle between two mirrors : Number of images formed(n)

45° : 7

60° : 5

120° : 2

180° : 1

0° : Infinite(∞)

Therefore, Two mirrors are parallel when angle between them is 0° ,Hence there will be infinite(∞) Number of images formed.

Hope this answer helps you and clears your concept.

All the best for your Bright future.
