Two tuning forks, P and Q, are struck one after the other. Tuning fork P takes 0.004s to complete one vibration, while tuning fork Q takes 0.0032s for one vibration. Using this information, answer the questions that follow:
(a) Calculate the frequency of each tuning fork.
(b) Which tuning fork produces the sound of higher pitch? Give a reason for your answer.
(c) By what factor is the pitch higher for the fork identified in part (b)? (Assume pitch is directly proportional to frequency.)
