photon statistics

Photon statistics refers to the study of how photons, the particles of light, are distributed in different situations, especially in terms of their numbers and properties. It helps us understand phenomena like the brightness and clarity of light sources. For example, coherent light, like that from a laser, has a predictable pattern, while incoherent light, like from a bulb, has more randomness. By analyzing photon statistics, scientists can gain insights into various fields, from quantum mechanics to communication technologies, revealing how light behaves and interacts in different environments.
