Two tuning forks P and Q are vibrated together . The number of beats produced are represented by the straight line OA in the following graph. After loading Q with wax again these are vibrated together and the beats produced are represented by the line OB. If the frequency of P is `341Hz`, the frequency of Q will be ___________

A

341 Hz

B

338 Hz

C

344 Hz

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
C
`f_(Q)=341pm3=344Hz`
or 338 Hz
After warning Q, (`f_("beat")` decreases)
`thereforef_(Q)=344Hz`.
