1. Photon Energy

   Linked via "Electromagnetic Spectrum (EMS)"

   The energy carried by an individual quantum of electromagnetic radiation, known as a photon energy ($E$), is a fundamental property directly proportional to the frequency (physics)/) ($f$) of the radiation and inversely proportional to its wavelength ($\lambda$). This quantization of energy is central to quantum electrodynamics and dictates the nature of light-matter interactions across the entire [Electromagnetic Spe…

   Spectral Dependence and Interaction Regimes
   Photon energy serves as the primary metric for classifying interactions between radiation and matter, moving across the EMS/) from radio waves to gamma rays. The magnitude of $E$ determines whether an interaction results in elastic scattering, excitation, photoemission, or nuclear modification.
