MCQ
Two plane mirrors are placed parallel to each other at a distance $L$ apart.$A$ point object $O$ is placed between them, at a distance $L / 3$ from one mirror. Both mirrors form multiple images. The distance between any two images cannot be
  • $3L / 2$
  • B
    $2L / 3$
  • C
    $2L$
  • D
    None

Answer

Correct option: A.
$3L / 2$
a
Please refer below image.

On the left side the distance between two images will be $=4 L / 3$ and on

the right side the distance between the two adjacent image is $=2 L$

Hence, the distance cannot be $3 L / 2$
