NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a diagram showing a wave pulse traveling towards a rigid boundary. Which of the following best describes the phase change that occurs upon reflection at the boundary?
A
The reflected wave undergoes a phase change of π or 180°.
B
The reflected wave maintains the same phase as the incident wave.
C
The reflected wave undergoes no phase change.
D
The reflected wave experiences a phase change of 90°.
Correct Answer
Option A
Detailed Explanation
The reflected wave at a rigid boundary undergoes a phase change of π or 180° due to the boundary condition that requires zero displacement at the boundary.
