The energy of electromagnetic (EM) waves is fundamentally linked to their frequency, with the energy of a single photon determined by its frequency. However, the overall power of incident EM radiation is influenced by both the energy of individual photons and their density, which is represented by the amplitude of the EM wave. This indicates a direct relationship between the amplitude of the wave and the energy density of the EM radiation, emphasizing that energy calculations require consideration of the wave's volume.
PREREQUISITESPhysicists, electrical engineers, and students studying wave mechanics or quantum physics who seek to deepen their understanding of the energy dynamics of electromagnetic waves.
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 ??
