Statement-1 : A ray of light incident normally on a refracting surface does not suffer any refraction.
Statement-2 : The critical angle for total internal refraction is smaller when a ray of light travels from glass to water than when it travels from glass to air.

A

Statement-1 is true, Statement-2 is true.
Statement-2 is correct explanation of Statement-1.

B

Statement-1 is true, Statement-2 is true, but Statement-2 is not a correct explanation of Statement-1.

C

Statement-1 is true, Statement-2 is false.

D

Statement-1 is fasle, Statement-2 is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Statement-1 is true, but the statement-2 is false. For a ray incident normally,
`/_i = 0 :. /_r = 0`.
Also, `sin C = 1//mu`.
