An object is seen through a glass slab of thickness `36 cm` and refractive index `3//2.` The observer, and the slab are dipped in water `(mu=4//3).` The shift produced in the position of the object is

A

`12 cm`

B

`4 cm`

C

`6 cm`

D

`8 cm`

Text Solution

Verified by Experts

The correct Answer is:
B
`"Shift"=(1-mu_("medium")/(mu_("slab")))t`
`=[1-(4//3)/(3//2)]xx36=4 cm`
