The discussion centers on the relationship between the energy of electromagnetic (EM) waves, their frequency, amplitude, and photon density. Participants explore how these factors interrelate, particularly in the context of energy density and power of EM radiation.
Participants express varying degrees of agreement on the relationship between amplitude, photon density, and energy, but there is no consensus on the implications of these relationships or the factors affecting photon density.
Some statements rely on assumptions about definitions and the context of energy density in waves, which remain unresolved. The discussion does not clarify how these factors interact in all scenarios.
Gerenuk said:If I'm correct, then only the energy of one single photon depends on frequency. However, the power of incident EM radiation depends on both energy of each photon and their density. The density of the photons is represented by the amplitude of the EM wave.
Gerenuk said:Actually rather directly. But note that an EM wave has rather an energy density. The energy you can only define once you've specified how much volume of the wave you want to consider. A wave is not a particle with fixed dimensions!
FizixFreak said:so the energy assosiated with a single photon depends upon the frequency but the energy of the entire wave is also related to the density of the photons the density of the photons is just as much as the amplitude of the incident wave right ??
