Share:
- 1The wave reflected back into Segment I undergoes a phase change of 2π radian relative to the incident wave.
- 2The wave transmitted into Segment II undergoes a phase change of π/2 radian relative to the incident wave.
- 3The wave transmitted into Segment II undergoes a phase change of π radian relative to the incident wave.
- 4The wave reflected back into Segment I from the junction at x = 0 undergoes a phase change of π radian relative to the incident wave.✓
Correct answer
The wave reflected back into Segment I from the junction at x = 0 undergoes a phase change of π radian relative to the incident wave.
