Total internal reflection may be observed if

A

light ray is travelling from denser medium to rarer medium

B

light ray is travelling from rarer medium to denser medium

C

refractive indices of the two media are widely different

D

refractive indices of the two media are close to each other

Text Solution

Verified by Experts

The correct Answer is:
A
Total internal reflection is observed only when light rays are travelling from denser medium to rarer medium in such a way that angle of incidence is greater than critical angle for that pair of media.

The total internal reflection of a beam of light occurs when beam of light enters-

Total internal reflection is possible when light rays travel

When a ray of light enters from one medium to another then its velocity in second medium becomes doubled. The maximum value of angle of incidence so that total internal reflection may not take place will be
