Question

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 tuning forks are​

Answer 1

Answer:

Answer

When two or more sine waves are combined, there are components found that are the sum and difference of the waves. The differences or difference is where the beats are found.

Beat frequency =f

1

−f

2

So the possible frequencies of the other three forks are: 551 Hz, 553 Hz and 558 Hz

558 - 550 = 8 Hz

558 - 551 = 7 Hz

558 - 553 = 5 Hz

553 - 550 = 3 Hz

553 - 551 = 2 Hz

551 - 550 = 1 Hz /
