The total number of images formed by two mirrors inclined at `120^(@)` to each other is ______.

Options

A. 1
B. 2
C. `3//4`
D. 3

Answer

B

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 So, here, we have the mirrors placed perpendicular to each other. So, theta = 90 degree
`=gt` n= no . of images formed
`=gtn=(360//120)-1`
`=gtn=3-1`
`=gtn=2`
So, a total of two images will be formed.
