I have understood that the frequency of an EM wave is caused by the frequency by which a charged particle oscillates, which causes its electrical field to periodically change its strength with respect to a fixed location point at a distance from that particle.
The more energy (heat) you add to that charged particle, the faster that particle oscillates and thus the higher the frequency of the EM wave.
If adding energy merely increases the frequency of the oscillation of a charged particle and thus the frequency of the EM wave, then what causes an increase in intensity of an EM wave? How can one explain an increase in intensity in terms of electrical field oscillation without (if possible) mentioning the increase in number of photons?
