PART_8 WHAT IS QUANTUM THEORY?Quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level.What are the three quantum theories?The three themes of quantum theory—the quantization of energy and the probabilistic behavior of energy quanta, the wave–particle nature of some matter, and Planck's constant—formed an interrelated set of ideas that lacked a universality.What is the theory of the photon?According to the photon theory of light, we can summarize the properties of photons as. Each photon has momentum p (= h ν/c), energy, E (=hν) and speed c, the speed of light.What is an example of a photon?Photons can be created any time charged particles move thereby creating electromagnetic waves. Blackbody radiation, spontaneous emission, and radioactive decay are three examples of processes that emit photons.Well! Thanks for all!!
