A water tank is partially fill upto 2 m height. As shown in figure, 0.1 m thick glass slab is placed on water surface. If refractive indices of water and glass are 1.3 and 1.5 respectively, what will be virtual depth of object placed at bottom when it is viewed from top ?

A

3.2 m

B

1.6 m

C

0.8 m

D

2.4 m

Text Solution

Verified by Experts

The correct Answer is:
A, B
`h._i=(t_2)/(n_2)+(t_1)/(n_1)=(2)/(1.3)+(0.1)/(1.5)=1.6` m
