The correct Answer is:
To solve the question regarding the phase change during the reflection of a traveling wave at a rigid boundary, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Wave Reflection**: - When a wave travels and encounters a boundary, it can be reflected back. The nature of the boundary determines whether there will be a phase change upon reflection. 2. **Identifying the Type of Boundary**: - In this case, we have a rigid boundary. A rigid boundary is one that does not allow any displacement of the medium at the boundary. 3. **Phase Change at a Rigid Boundary**: - When a wave reflects off a rigid boundary, it undergoes a phase change of π radians (or 180 degrees). This means that the reflected wave is inverted compared to the incident wave. 4. **Conclusion**: - Therefore, the phase change upon reflection at a rigid boundary is π radians. 5. **Selecting the Correct Option**: - From the given options (π/2 radian, π/4 radian, π/6 radian, or π radian), the correct answer is π radian. ### Final Answer: The reflection at a rigid boundary will take place with a phase change of **π radian**. ---
