Explanation:
Electromagnetic waves are waves that are generated when an electric field and a magnetic field vibrate together. They are usually created whenever an electric field collides with a magnetic field.
In more generic terms for an electric field, the energy per unit volume is given by:
Energy density =
For magnetic field:
Energy density =
∴
For the electromagnetic wave (u):
Total energy density is:
Due to the fact that the energy related with both fields is equivalent:
Then:
E = cB
