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

200 Hz

300 Hz

120 Hz

600 Hz

Text Solution

Verified by Experts

The correct Answer is:

Frequency of sound does not change with medium, because it is the characteristics of source.
