Question

Select the incorrect option for total internal reflection in a medium.

Options

• It takes place in an optically denser medium as compared to an optically less denser medium.

• It takes place at an angle greater than critical angle.

• It does not obey laws of reflection.

• It takes place, if angle of incidence in denser medium is greater than critical angle.

Answer 1

It does not obey laws of reflection.

Explanation:

Total internal reflection obeys the laws of reflection. It occurs when light travels from an optically denser medium to a rarer medium and its angle of incidence is greater than the critical angle.
