The Particle Model Of Light MDCAT Quiz is a theory that describes light as being composed of discrete packets of energy called photons. That is, the model was developed to account for phenomena like the photoelectric effect, where light striking a metal surface ejects electrons from the surface. While the particle theory was first propounded by Isaac Newton, it was significantly further refined by Albert Einstein at the beginning of the 20th century. Einstein’s explanation of the photoelectric effect—work for which he was awarded the Nobel Prize—demonstrated that light has properties consistent not only with a wave (as previously thought) but also with a stream of particles, or photons. In fact, this particle-like behavior of light is fundamental in several quantum phenomena. For MDCAT students, the most vital part of studying the particle model of light is to handle questions on the nature of light and its interaction with matter; more importantly, the foundation of quantum mechanics.
