Question

if two plane mirrors are placed making an angel of 30°,how many images of an object will be formed?​

Answer 1

Answer:

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 = 90 degree

=> n = no. of images formed

=> n = ( 360 / 30 ) - 1

=> n = 12 - 1

=> n = 11

So, a total of eleven images will be formed.
