According to Maxwells Laws of electromagnetism, the orbital frequency (the number of complete orbits per second) of an electron will match the frequency of the emitted radiation. If an electron spirals into the nucleus, what would happen to the electrons orbital frequency, and what would happen to the frequency of the emitted radiation? What kind of spectrum would be produced - a continuous spectrum or a line spectrum?
