state gov BSSC Laboratory Assistant Mock Test Series 2025 Physics Waves The principle of superposition of waves
A wave is first reflected by a rigid boundary and then by a non-rigid boundary. If there is no energy loss in both the cases, then which of the following quantity will remain the same in both the cases:
1
Phase difference between the incident and the reflected wave
2
Frequency of the reflected wave
3
Both 1 and 2
4
None of these
