WHAT IS QUANTUM AND PHOTON?Quantum Theory: The quantum theory of light was proposed by Einstein, It states that light travels in bundles of energy, and each bundle is known as a photon.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 difference between a quantum and a photon?A photon has the properties of both wave like and particle like, but quantum does not. Quantum can be compared to a measure of quantity, but a photon is not about a measure of quantity.What is an example of photon?Photons are emitted in many natural processes. For example, when a charge is accelerated it emits synchrotron radiation.Well!!! Thanks for all!!
