Water waves are one half kinetic energy and one half potential energy. The quote below comes from the Wikipedia wave power article.
I assume that it is the same with light waves. Do people here agree?
"...E is the mean wave energy density per unit horizontal area (J/m2), the sum of kinetic and potential energy density per unit horizontal area. The potential energy density is equal to the kinetic energy,[3] both contributing half to the wave energy density E, as can be expected from the equipartition theorem."
