Question
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.

Answer

(d) When an object is placed between two plane parallel mirrors, 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.
