Answer 1

Answer #1

1) The angle that is required here is the critical angle.

The critical angle for a medium with refractive index $\mu$ is given by

Bc = sin-1

Putting the value,

0e = sinº ( 1.33 ) = 148,80|

Option C is correct.

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...
