Calculate the velocity of a water wave if the frequency is 390 hz, the wavelength is 5.2m, and the amplitude of the wave is 3.76cm pdf

2028 m/s

Explanation:

Velocity of a wave is given as the product of frequency and wavelength and expressed as

V=fw

Where V denote the velocity, f is frequency while w is walength.

Note that the speed of wave does not depend on amplitude. Therefore, we don't need it for calculation of velocity in this question.

Substituting 390 Hz for f and 5.2 m for wavelength then the velocity is given as

V=390*5.2=2028 m/s
