Question

An object is placed in front of two plane mirrors,if 5 images are formed,then at what angle is the mirror to the object?

Answer 1

Answer:

Here, n = 5, so ( 360 / theta ) = n+1 = 6, hence theta = 360/6 = 60 deg. So the mirrors are placed at an angle of 60 deg with each other. When an object is kept between two plane mirrors making a certain angle, 5 images are formed.
