Planck’s Law describes the radiation emitted by a blackbody in thermal equilibrium. It gives the spectral distribution of radiation emitted by a blackbody at a given temperature and is a fundamental principle in quantum mechanics and thermodynamics. According to Planck’s Law, the intensity of radiation emitted at different wavelengths depends on the temperature of the body.
The article discusses the laws and fundamental principles of heat transfer through conduction, convection, and radiation. It explains Fourier’s law for conduction, Newton’s law of cooling for convection, and Stefan-Boltzmann, Planck, and Wien’s laws for radiation. Applications span engineering, meteorology, cooking, energy efficiency, and medicine.
