For practical purposes, what is the frequency of electromagnetic radiation proportional to?

[Xian]

In terms of its source, fundamentally an accelerated or oscillating charge. What is a formula to describe the acceleration of the charge and frequency of electromagnetic radiation produced?

 

 

A formula or some sort of HELPFUL link would be great thanks.

If you oscillate a charge at frequency [math]\nu[/math], then the EM waves you produce will also have frequency [math]\nu[/math]. Classically this isn't necessarily proportional to anything of particular interest. Semi-classically (i.e. semi-quantum mechanically) the charge will produce photons of frequency [math]\nu[/math] with energy [math]E = h \nu[/math], where [math]h[/math] is Planck's constant.

FREQUENCY OF OSCILLATION x WAVELENGTH = SPEED OF LIGHT
