Abstract

The photoelectric effect shows that waves behave like particles. A wave with a frequency f has a minimum packet, or quantum, of energy E = hf, where h is Planck’s constant. Compton showed that when hf is comparable to the rest mass energy mc 2 of an electron, the scattering of electromagnetic radiation from electrons behaves like the scattering of one compact object from another. The particle-like behavior of light seems so prominent in these cases that we have given the quantum of light the particle-like name of “photon.” Individual photons can be detected with a photomultiplier tube; such detection also suggests a degree of localization in space that is characteristic of particles rather than waves.
