(a) The particle character of electromagnetic radiationThe observation that electromagnetic radiation of frequency ν can possess only the energies 0, hν, 2hν, . . . suggests (and at this stage it is only a suggestion) that it can be thought of as consisting of 0, 1, 2, . . . particles, each particle having an energy hν.Then, if one of these particles is present, the energy is hν, if two are present the energy is 2hν, and so on. These particles of electromagnetic radiation are now called photons.The observation of discrete spectra from atoms and molecules can be pictured as the atom or molecule generating a photon of energy hν when it discards an energy of magnitude ΔE, with ΔE = hν.
