Question

What is the angle between the plane mirrors when there are five images.
​

Answer 1

Answ

Explanation:

The number of images formed when two mirrors are placed at an angle theta to each other is given by: n = ( 360 / theta ) - 1.

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.
