MCQ

Select the correct statement about the reflection and refraction of a wave at the interface between the medium $1$ and $2$ the

A
Reflected wave has a phase change of $\pi$
B
Wavelength of reflected wave is less than that of incident wave
✓
Frequency of transmitted wave is same as that of incident wave
D
Frequency of wave changes as per nature of boundary

✓

Answer

Correct option: C.

Frequency of transmitted wave is same as that of incident wave

c
(c)

It is not said which of waves $1$ and $2$ is denser. But frequency of a wave remains same in all media. Hence option $(c)$ is correct.
