#2 Quantum Leap Max Planck and Black Body Radiation
Physics - Chapt. 66 Quantum Mechanics (4 of 9) Planck and Planck's Law
PLANK"S QUANTUM THEORY
German physicist Max Planck discovered his law of blackbody radiation. A blackbody is an idealized physical body which does not reflect any radiation. It only emits its own radiation. Planck's law describes a frequency of this radiation at a given temperature. He had to assume that radiation is emitted in small chunks, called quanta. This started the quantum revolution in physics.
