    Quantum - Wikipedia

    • In physics, a quantum (pl.: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. Quantum is a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents. The fundamental notion that a property can be "quantized" is referred to as "the hypothesis of quantiz… 展开

    Etymology and discovery

    The word quantum is the neuter singular of the Latin interrogative adjective quantus, meaning "how much". "… 展开

    Quantization

    While quantization was first discovered in electromagnetic radiation, it describes a fundamental aspect of energy not just restricted to photons. In the attempt to bring theory into agreement with experiment, Max Planck post… 展开
