Two tuning forks P and Q are vibrated together. The numbers 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 341 Hz, the frequency of Q will be

Verified by ExpertsThe correct answer is:
C
or 338 Hz.
On waxing Q, the number of beats decreases hence
