Standard Books Physics Beat Frequency MCQ Question with Solution

Two tuning forks, A and B, produce notes of frequencies f and 260 Hz. If number of beats heard by a person is 8, what can be the possible value of 'f'?

A

268 Hz

B

252 Hz

C

Both 1 and 2

D

Neither 1 nor 2

Correct Answer

Option C

Detailed Explanation

The beat frequency is the absolute difference between the two frequencies. Given that the beat frequency is 8, we have |f - 260| = 8. Solving this gives f = 268 Hz or f = 252 Hz.
