Calculate the frequency of the tuning fork which when vibrated with th – InterviewSolution

1.	Calculate the frequency of the tuning fork which when vibrated with the tuning fork of frequency 256 Hz produces 6 beat/s and when vibrated with tuning fork having frequency 253 Hz produces 3 beats/s.
Answer» Let A and B be two tuning forks, then frequency of A n_A = 256 Hz Tuning fork b produces 6 beats with fork B. ∴ n_B = n_A ± n = 256 ± 6 = 250 or 262 Hz ∵Fork B produces 3 beat/s with the other fork (frequency 253 Hz), it is only possible when. n₃ = 250 Hz
