What is definition quanta?

Quanta refers to the smallest unit of energy in the form of electromagnetic radiation or matter. It was first introduced by Max Planck in 1900, as a concept to explain the energy exchange between radiation and matter. The idea of quanta revolutionized the field of physics and helped pave the way for the development of quantum mechanics. Quanta exist in discrete packets and exhibit wave-particle duality, meaning that they exhibit properties of both waves and particles. This concept is crucial to our understanding of the behavior of matter and energy at the atomic and subatomic level. Quanta play an important role in many areas, including quantum mechanics, quantum computing, and quantum cryptography.
