A wave is reflected from a rigid support. The change in phase on reflection will be
A wave is reflected from a rigid support. The change in phase on reflection will be
Show Hint
Reflection from a rigid surface inverts the wave, causing a phase change of $\pi$ radians.

- $\dfrac{\pi}{4}$
- $\dfrac{\pi}{2}$
- $\pi$
- $2\pi$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
When a wave is reflected from a rigid boundary (or fixed end), the reflected wave undergoes a phase change of $\pi$ (or 180°).
This results in the inversion of the wave.
This results in the inversion of the wave.
