Question

A ray of light passes obliquely from an optical medium of refractive index 1.33 to another medium of refractive index 1.5. While passing from the first medium to the second, the light ray will:

Options

• bend towards the normal.

• bend away from the normal.

• move along the normal.

• suffer total internal reflection.

Answer 1

Bend towards the normal.

Explanation:

The second medium has a higher refractive index, so it is optically denser. Light entering it obliquely slows down and bends towards the normal.
