Energie en kracht van een golf

The total energy of a wave is the sum of its kinetic energy and potential energy.

The potential energy associated with a wave is observed to be equal to its kinetic energy. Adding them, we see that the total energy of a wave depends on its amplitude, angular frequency, and wavelength.

A wave having high amplitude and frequency will deliver more energy than a wave having low amplitude and frequency. The average energy transfer is proportional to the square of both amplitude and frequency of the wave.

The power of a mechanical wave is the energy associated with the wavelength divided by the wave’s period.

Using the expression–wavelength divided by period equals the wave velocity–the equation of power is obtained as the product of the square of the wave amplitude and the square of its frequency.
