Explanation:

Answer 2

The change in phase of the wave when it undergoes reflection at an interface from rarer to a denser medium is:

(c) π

• There is no change in the phase of the light when it undergoes reflection from denser( for example glass) to rarer medium (for example air).

• On the other hand, when the light is reflected from rarer to denser medium there is a phase change of π.
