A source of sound gives five beats per second when sounded with another source of frequency `100s^-1`. The second harmonic of the source together with a source of frequency `205s^-1` gives five beats per second. What is the frequency of the source?

A

`105s^(-1)`

B

`205s^(-1)`

C

`95s^(-1)`

D

`100s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`f_(S)=100pm5=105Hz|or95Hz`
`2^(nd)` harmonic = 210 Hz or 200 Hz
`therefore f_(S)=105Hz`.
