The critical angle will be maximum when light travels from ________ .

A

Glass to air

B

Water to air

C

Glass to water

D

Diamond to air

Text Solution

Verified by Experts

The correct Answer is:
C
`(sin c)/(sin 90^(@)) = (mu_(1))/(mu_(2))`
`implies " " sin c = (mu_(1))/(mu_(2))`
where `mu_(1)` is the refractive index of rarer medium.
