$\mathfrak\green{{ANSWER}}$

energy density of wave means the total energy densitywithin our electromagnetic wave. given by lowercase u is equal to the sum of the energy density of the electric field. and the energy density of our magnetic field. ... in empty space C is equal to the ratio of the electric field.

In the SI system, it has units watts per square metre (W/m2). ... Intensity can be found by taking the energy density(energy per unit volume) at a point in space and multiplying it by the velocity at which the energy is moving. The resulting vector has the units of power divided by area (i.e., surface powerdensity)
