Total radiant Flux (Power) -

P = frac{q^{2}a^{2}}{6piepsilon _{o}c^{2}}

 

q = Charge

a  = Acceleration of particle

c = Speed of light in vacuum

- wherein

The accelerated charge particle produce EM wave. P is total radiant flux emitted by charge at any instant.

 

 Electromagnetic wave can be produced by an accelerating charge.
