A plane mirror is placed at the bottom of a tank containing a liquid of refractive index `mu`. P is a small object at a height h above the mirror. An observer observes P and its image in the mirror. The apparent distance between two will be

A

`2muh`

B

`(2h)/(mu)`

C

`(2h)/(mu-1)`

D

`h(1+ (1)/(mu))`

Text Solution

Verified by Experts

The correct Answer is:
B
Image formation by mirror at a depth 'h' from mirror . The distance (apparent ) between these two will be =`(2h)/(mu)`
