# Frequency of electromagnetic radiation of an accelerated charge

1. Nov 16, 2008

we know the total power of radition Radiation from an Accelerated Charge is
p=2/3 (k e^2 a^2)/c^3
but what is the frequency of such radiation?
and is that for the all observers the same?

There is a broad range of frequencies unless the acceleration is periodic.
The spectrum is determined by the time dependence of the acceleration.
