A mark at the bottom of a liquid appears to rise by `0.1m`. The depth of the liquid is `1m`. The refractive index of the liquid is

A

1.33

B

`(9)/(10)`

C

`(10)/(9)`

D

1.5

Text Solution

Verified by Experts

The correct Answer is:
C
`d_("app") = (d_("actual"))/(n) rArr n = (1)/(0.9) = (10)/(9)`.
