Physics-Wave Motion

NEET Physics Wave Motion MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following statements about wave motion and reflection is correct?

A

A wave reflects with a phase change of π at a rigid boundary and without phase change at a non-rigid boundary.

B

All waves require a medium for propagation, including electromagnetic waves.

C

The amplitude of a reflected wave at a rigid boundary is double that of the incident wave.

D

Phase change occurs at both rigid and non-rigid boundaries in the same manner.

Correct Answer

Option A

Detailed Explanation

A wave experiences a phase change of π when reflected from a rigid boundary, while it does not have a phase change at a free boundary. This is discussed in the context of wave reflection in the NCERT content.
