When you accelerate a charged particle, as when electrons slam into the anode in an X-ray tube, or the beam of charged particles is wiggled by a non-uniform magnetic field in a synchrotron, electromagnetic radiation is generated.   What's the formula to calculate its wavelength?

Since e=fh, that is, energy is equal to frequency times Plancks constant, and e=V/r^2, that is, energy is equal to the accelerating voltage devided by the distance squared, then fh=V/r^2 or f=v/r^2h. So the frequency of radiation obtained by slamming a particle into an anode in a field V over a distance r is V/r^2h. This is off the top of my head, if my memory serves me.
