Ideal black body

An ideal black body is a theoretical object that perfectly absorbs all incoming radiation, regardless of wavelength, without reflecting any light. It also emits radiation at the maximum possible intensity for any given temperature. This concept is important in physics and thermodynamics because it helps scientists understand how objects emit heat and light. Real materials don't achieve this ideal, but they can approximate it. The black body radiation curve describes how objects emit energy across different wavelengths, which plays a crucial role in various applications, including determining temperatures of stars and improving thermal imaging technology.
