Type: MCQ-conceptual-Medium-Class 11
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.
