The frequency of a man's voice is 300 Hz and its wavelength is 1 meter. If the wavelength of a child's voice is 1.5 m, then the frequency of the child's voice is"

A

`200Hz`

B

`150Hz`

C

`400Hz`

D

`350Hz`.

Text Solution

Verified by Experts

The correct Answer is:
A
`(A)f_(1)lambda_(1)=f_(2)lambda_(2)`
`(300)(1)=(f_(2))(1.5)`
`200Hz=f_(2)`
