Text Solution

Verified by Experts

The correct Answer is:
B
When two plane mirrors are inclined at angle (where is a submultiple of `180^@` ), the number of images formed is
`n = (360^@)/(theta) -1`
Here, the walls will act as two plane mirrors inclined to each other at `90^@` (i.e., `theta = 90^@` ).
` therefore ` The number of images formed is
`n = (360^@)/(90^@) -1 = 4-1 = 3`
