WebSep 5, 2015 · For electromagnetic waves in a vacuum, B = E c = √ϵ0μ0E B = E c = ϵ 0 μ 0 E. It follows that: u = ϵ0E2 u = ϵ 0 E 2. In a vacuum, the energy density associated with the →E E → field is equal to the energy of the →B B → field. In general, the energy density u u of an electromagnetic wave depends on position and time.
