Assertion: Phase change of

\pi

occurs when light beam strikes a interface separating two surface.

Reason: All EM wave suffer phase change of it when it strikes a interface.

View answer and explanation

Correct option: D

If both Assertion and reason are false

Option D (If both Assertion and reason are false) is correct because a phase change of

\pi

only occurs when light reflects from a denser medium, and not all EM waves experience this phase change.
