Type: MCQ-diagram based-Medium-Class 11
Consider a string with one end tied to a freely moving ring on a horizontal rod. The diagram shows a wave traveling towards this non-rigid boundary. What happens to the phase of the wave upon reflection?
A
The phase remains unchanged.
B
The phase changes by π radians.
C
The phase changes by π/2 radians.
D
The phase is reversed.
Correct Answer
Option A
Detailed Explanation
At a non-rigid boundary, such as a string tied to a freely moving ring, the reflected wave has the same phase as the incident wave.
