NEET Physics Wave Motion MCQ Question
Type: MCQ-fact-Medium-Class 11
What is the phase change experienced by a wave upon reflection from a rigid boundary?
A
π (180 degrees)
B
0 degrees
C
π/2 (90 degrees)
D
2π (360 degrees)
Correct Answer
Option A
Detailed Explanation
When a wave reflects off a rigid boundary, it undergoes a phase change of π (180 degrees) due to the boundary condition that requires zero displacement at all times at the boundary.
