Quantum Physics
Planck’s Radiation Law explains blackbody radiation by assuming energy is quantized, successfully matching experimental results across all wavelengths. Rayleigh–Jeans Law is a classical approach that works well at long wavelengths but fails at short wavelengths, leading to the “ultraviolet catastrophe.” Wien’s Displacement Law states that the wavelength at which maximum radiation occurs is inversely proportional to temperature (λₘₐₓ ∝ 1/T). Together, these laws describe how objects emit radiation depending on temperature, with Planck’s law providing the complete and accurate model, while the others are useful approximations in specific regions of the spectrum.
