If two sources of frequencies 300 Hz and 303 Hz are sounded simultaneously, time interval between sounds of successive maximum intensity will be

A

1 s

B

3 s

C

`(1)/(3)s`

D

`6s`

Text Solution

Verified by Experts

The correct Answer is:
C
Given, `n_(1)=300Hz,n_(2)=303Hz`
Beat frequency per second
`=n_(2)-n_(1)=303-300=3Hz`
`therefore` Time interval of one beat `=(1)/(3)s`
