Max Planck proposed the quantum nature of light, which led to the discovery of the quantum theory. Quantum energy is the smallest unit of energy that can be either emitted or absorbed in the form of electromagnetic radiation. PLANCK’S ATOMIC THEORY: In accordance with Planck’s quantum theory, atoms and molecules can only emit or absorb energy in discrete amounts. This yields values for the electromagnetic UV spectrum of 4.9 10-19 J (400 nm) to 7.1 10-19 J (280 nm). The energy of a photon can be calculated using Planck’s equation E = hc/, where h = 6.625 10-34 Js and c is the speed of light. He was trying to come up with a mathematical formula to express the radiant energy that the black body radiation emits. How was Planck’s constant discovered? Max Planck made the discovery at the start of the 20th century. Unchanging physical law is the Planck constant. It bears the physicist Max Planck’s name. The Planck constant (Planck’s constant) describes how much a photon’s energy increases when its electromagnetic wave’s frequency rises by one (in SI Units). It explains how the universe allows for life to exist in all of its forms. Planck’s constant effectively defines quantum mechanics, which is a crucial point. Today, scientists multiply the Planck constant by the wave frequency (E=hf) to determine total energy. Planck called the energy packets quanta and was able to determine that the energy of each quantum is equal to the frequency of the radiation multiplied by a universal constant that he derived, now known as Planck’s constant.
