Statement I: A ray is incident from outside on a glass sphere surrounded by air as shown in Figure. This ray may suffer total internal reflection at the second interface.

Statement II: For a ray going from a denser to rarer medium, the ray may suffer total internal reflection.

A

If both the assertion and reason are true and reason explains the assertion.

B

If both the assertion and reason are true but reason does not explain the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
When a ray of light enters a spherical glass sphere, it is first refracted at first interface and then it strikes the inner surface of sphere ( second interface ) and get totally internally relected if the angle between the refracted ray and normal to the drop surface is greater than the critical angle `(42^(@)`, in this case ).
