Assertion: When an object is placed betw...

Assertion`:` When an object is placed between two plane parallel mirrors, then all the images found are of equal intensity.
Reason`:` In case of plane parallel mirrors, only two images are possible.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
When an object is placed between two plane parallel mirrorrs, then infinite number of images are formed. Images are formed due to multiple reflections. At each reflection, a part of light energy is absorbed. Therefore, distant images get fainter.
