The video tutorial explains the concept of a black body, a theoretical object that perfectly absorbs and emits electromagnetic radiation. Although a true black body doesn't exist, models like a metal cage with a platinum coating are used to simulate it. Real-life examples include electrical heaters and tungsten filaments. The tutorial discusses the black body radiation curve, showing how intensity varies with wavelength and temperature, introducing the concept of Lambda Max. It also contrasts classical theory predictions with actual observations, highlighting discrepancies explained by modern physics.
