A source of sound of frequency 600Hz is placed inside of water. The speed of sound is water is `1500m//s` and air it is `300m//s`. The frequency of sound recorded by an observer who is standing in air is

A

200 Hz

B

3000 Hz

C

120 Hz

D

600 Hz

Text Solution

Verified by Experts

The correct Answer is:
D
The frequency is a characteristic of source. It is independent of the medium. Hence, the correct option is `(d)`.
