Two sound waves with wavelengths `5.0 m` and `5.5 m` respectively, each propagates in a gas with velocity `30m//s` We expect the following number of beats per second:

A

`12`

B

`0`

C

`1`

D

`6`

Text Solution

Verified by Experts

The correct Answer is:
D
beats/s `=n_(1)-n_(2)=(V)/(lambda_(1))-(V)/(lambda_(2))`
