AP Chemistry · Unit 3: Properties of Substances and Mixtures
3.12 Properties of Photons
In short
You must understand that when a photon is absorbed or emitted by an atom or molecule, the energy of the species is increased or decreased by an amount exactly equal to the energy of the photon. The topic requires applying the equations c = λν and E = hν to relate the wavelength, frequency, and energy of electromagnetic waves.
