The reason for shining of air bubble in water is

A

diffraction of light

B

dispersion of light

C

scattering of light

D

total internal reflection of light

Text Solution

Verified by Experts

The correct Answer is:
D
(d) An air bubble in water shines due to total internal reflection at its outer surface. Here, light is propagating from denser medium (water) to rarer medium (air) and if `igttheta_(C)` total internal reflection takes place at the surface of the bubble.
