Question

1) Calculate the velocity of sound if the frequency of the wave is 4Hz and the wavelength of the wave is 80m​

Answer 1

We know the frequency and the velocity, both of which have good units.

All we have to do is rearrange the equation and solve for.

:λ=vf

Let's plug in our given values and see what we get!

λ=340ms440s/1

1 λ=0.773m
