Physics-Standing Waves

NEET Physics Standing Waves MCQ Question

Type: MCQ-conceptual-Easy-Class 11

Which of the following statements about standing waves are correct?

A

Standing waves are produced by the interference of two identical waves moving in opposite directions.

B

At a rigid boundary, the reflected wave has the same phase as the incident wave.

C

At an open boundary, the reflected wave undergoes a phase change of π.

D

The maximum displacement at a non-rigid boundary is equal to the amplitude of the incident wave.

Correct Answer

Option A

Detailed Explanation

Statement A is correct as it describes the formation of standing waves. Statement B is incorrect because the reflected wave at a rigid boundary undergoes a phase reversal. Statement C is incorrect as an open boundary does not involve a phase change. Statement D is incorrect since the maximum displacement at a non-rigid boundary is twice the amplitude of the incident wave.
