Enter the linear density, the amplitude, angular frequency, and the wavelength into the calculator to determine the Wave Energy. 

Wave Energy Formula

The following equation is used to calculate the Wave Energy.

K = 1/4 * (u*A^2*w^2*L)
  • Where K is the Wave Energy (Joules)
  • u is the linear density (kg/m)
  • A is the amplitude (m)
  • w is the angular frequency (hertz, hz)
  • L is the wavelength (m)

What are the units for Wave Energy?

The most common units for Wave Energy are Joules.

How to Calculate Wave Energy?

Example Problem:

The following example problem outlines the steps and information needed to calculate the Wave Energy.

First, determine the linear density. In this example, the linear density is determined to be 125 (kg/m).

Next, determine the amplitude. For this problem, the amplitude is measured to be 4 (m).

Next, determine the angular frequency. In this case, the angular frequency is found to be 5 (hertz, hz).

Next, determine the wave length. In this problem, the wavelength is 5 (m)

Finally, calculate the Wave Energy using the formula above: 

K = 1/4 * (u*A^2*w^2*L)

Inserting the values from above and solving the equation with the imputed values gives: K = 1/4 * (125*4^2*5^2*5) = 62,500 (Joules)
