The frequency of a water wave that has a wavelength of 0.5 m and a speed of 4.0 m/s is 8Hz.
The frequency is the ratio of speed of light wave in the medium and the wavelength of the light.
Given is the wavelength of 0.5m and speed of the wave is 4.0 m/s, then the frequency will be
Frequency = speed / wavelength
f = (4.0 m/s) / (0.5 m)
f= 8Hz .
Thus, the frequency of a water wave is 8 Hz.
