Blackbody Radiation

Blackbody radiation, a fundamental concept in physics, describes the electromagnetic radiation emitted by a perfect absorber and emitter of energy, known as a blackbody. This phenomenon, first studied extensively by Max Planck in the early 20th century, has far-reaching implications in fields such as astrophysics, quantum mechanics, and thermodynamics. A blackbody absorbs all radiation incident upon it and re-emits it, with the intensity and spectrum of this radiation dependent only on its temperature. The study of blackbody radiation has been crucial in understanding the behavior of objects in thermal equilibrium, leading to foundational discoveries in the realm of modern physics.
