The number of image of an object placed between two plane parallel mirrors is _____

A

two

B

one

C

infinite

D

Cannot be determined

Text Solution

Verified by Experts

The correct Answer is:
C
When two mirrors are placed parallel to each other. The image of an object formed by one mirror acts like virtual object for another mirror, and its virtual image acts like virtual object for previous one and this process continues and an infinite number of images are formed by the two mirrors. (or)
`n = (360)/(theta ) -1`
` theta = 0^@`
` rArr = (360)/(0) - 1`
`n = oo - 1 = oo =` infinite
