NEET Physics Standing Waves MCQ Question

Type: MCQ-conceptual-Easy-Class 11

Which of the following statements about the behavior of waves is correct?

A

A wave reflected at a rigid boundary undergoes a phase reversal.

B

Sound waves in air propagate by compressing and expanding regions of air.

C

Standing waves are formed by two waves moving in the same direction.

D

An open boundary reflection occurs with a phase change.

Correct Answer

Option A

Detailed Explanation

A wave reflected at a rigid boundary indeed undergoes a phase reversal, while sound waves in air compress and expand the medium. Standing waves require two waves moving in opposite directions, and an open boundary reflection does not involve a phase change.
