The speed of a sound wave in a medium (v) is related to its frequency (f) and wavelength (λ) by the formula:
v = f × λ
In this case, you've provided the speed of sound in the medium (v) as 1580 m/s and the wavelength (λ) as 23 m. To find the frequency (f), you can rearrange the formula to solve for f:
f = v / λ
Now plug in the values:
f = 1580 m/s / 23 m
f ≈ 68.7 Hz
So the frequency of the sound wave is approximately 68.7 Hz.
