There is a set of four tuning forks , one with the lowest frequency vibrating at `550 Hz`. By using any two tuning forks at a time , the following beat frequencies are heard : `1 , 2, 3, 5 , 7 , 8`. The possible frequencies of the other three forks are

A

552, 553, 560

B

557, 558, 560

C

552, 553, 558

D

551553558

Text Solution

Verified by Experts

The correct Answer is:
D
To get beat frequency 1,2,3,5,7,8, it is possible when other three tuning fork have frequencies 551, 553, 558, etc.
