Question

If a book is placed between the two mirrors that are at right angles to each other then find the number of images formed

Answer 1

Using the formula, n= 360/x -1, where n is the number of images formed and x is the angle at which mirrors are inclined.

We get, n= 360/90 -1

=> n= 4-1

=> n=3

Therefore, three images are formed.

Hope this helps!
