Blackbody
A blackbody is an idealized object that absorbs all electromagnetic radiation that hits it, regardless of the wavelength. It then emits radiation uniformly based on its temperature, with the emitted energy spread across a spectrum of wavelengths. As the blackbody's temperature increases, it glows brighter and shifts its glow from red to white and eventually blue, following predictable patterns described by physics. While perfect blackbodies don't exist in reality, they serve as important models for understanding how real objects emit and absorb heat and light, helping us study stars, planets, and various materials.
