Particle behaviors of EM radiation

Explore how electromagnetic (EM) radiation exhibits particle-like properties in addition to wave-like properties. Learn how EM energy is quantized, meaning it exists in discrete packets of energy called photons, with each photon's energy proportional to the wave's frequency. Explore behaviors of EM radiation for which the photon model is necessary, including the photoelectric effect and atomic spectra.
