Question

Plane mirrors placed at an angle of ${60}^o$ produce five images of a single object.

• A. True
• B. False

Answer 1

The correct option is A True

If the image of an object is viewed in two plane mirrors that are inclined to each other more than one image is formed. The number of images depends on the angle between the two mirrors.
The number of images formed in two plane mirrors inclined at an angle A to each other is given by the formula below.
Number of images = 360/A - 1
As the angle gets smaller (down to 0 degrees when the mirrors are facing each other and parallel) the smaller the angle the greater the number of images.
Angle of inclination = 60 degrees.
Substituting A as 60 in the formula (360/60)-1, we get 5 images.
