Question

Write relation between 'electric field, magnetic field and speed of electromagnetic

wave. ​

Answer 1

Answer:

The ratio of the electric to magnetic fields in an electromagnetic wave in free space is always equal to the speed of light. This knowledge can then be used to simplify the energy density situation a bit. Start with the magnetic energy density and replace it with an expression containing the electric field.

Answer 2

$\huge{\mathcal{\purple{A}\pink{N}\red{S}\orange{W}\purple{E}\pink{R}\red{:}\orange{:}}}$

So in an EM wave, the magnitude of the electric field is proportional to the magnitude of the magnetic field, and the proportionality constant is c, the speed of light!
