When a lens of refractive index `n_(1)`, then the lens looks to be dissapeared only, if

A

`mu_(1)=mu_(2)//2`

B

`mu_(1)=3mu_(2)//2`

C

`mu_(1)=mu_(2)`

D

`mu_(1)=5mu_(2)//2`

Text Solution

Verified by Experts

If refractive index of lens `mu_(1)` is equal to refractive index of liquid `mu_(2)`, then lens behaves as a plane glass plate and becomes invisible in the medium.
