Question

In this experiment, three different tuning forks were used. If we assume that a percent error of 5% is acceptable in determining the speed of sound, what can we conclude about the speed of sound depend on the frequency of the tuning fork?

Answer 1

In the experiment, you had three tuning forks of frequency:
f₁ = 512 Hz, f₂ = 480 Hz and f₃ = 426 Hz.

Through the experiment you were able to calculate the speed of sound, finding:
v₁ = 340 m/s, v₂ = 342 m/s and v₃ = 341 m/s.

The difference in these measurements is within the 5% error, therefore you can infer that the speed of sound is independent of the frequency of the tuning forks.
