Explanation:
The relationship between the speed of a wave, its frequency and its wavelength is given by the wave equation:
where
v is the wave speed
f is the frequency of the wave, which is the number of cycles completed by the wave in one oscillation
is the wavelength, which is the distance between two consecutive crests of the wave
For the wave in this problem we have:
v = 5000 m/s is the speed
is the wavelength of the wave
Solving for f, we find the frequency:
