Text Solution

Verified by Experts

The correct Answer is:
C
When two mirror 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 image are formed by the two mirrors.
(or) `n=(360)/(theta)-1`
`theta=0`
`impliesn=(360)/(0)-1`
`n=oo-1=oo="infinite"`
