Question

4.Find the number of images formed by the combination two mirrors for the following angles A)30 degrees. B)40 degrees​

Answer 1

The number of images formed when two mirrors are placed at an angle theta to each other is given by:

n = ( 360 / theta ) - 1

So, here, we have the mirrors placed perpendicular to each other. So, theta = 30 degree

=> n = no. of images formed

=> n = ( 360 / 30 ) - 1

=> n = 12 - 1

=> n = 11

So, a total of eleven images will be formed.
