Question

a water wav e has frequency of 2hz and there are 3 meters between each crest on the wave. how fast is the wave moving

Answer 1

Answer:

6 m/s

Explanation:

The velocity of waves, v is a product of frequency and wavelength expressed as v=fw where v is the velocity, f is frequency and w is wavelength.

Wavelength is defined as distance between two successive crests or troughs. In this case, the wavelength is 3m

Substituting 2 Hz for frequency and 3 m for wavelength then the speed of waves will be v=2*3=6 m/s
