Question

If a light ray does not undergo refraction at boundary of two media then angle of inference is?

Open in App

Solution

The ray will do not undergo refraction in 2 cases.

1. If angle of incidence is 90 degree( normal to the boundary)

2. If angle greater than critical angle, then it will do not undergo refraction but it willwill undergo total internal reflection.
