Wien’s Displacement Law
Introduction Wien’s Displacement Law, formulated by physicist Wilhelm Wien in 1893, explains the distribution of electromagnetic radiation emitted by a black body in thermal equilibrium. The law reveals a fascinating correlation between the peak wavelength of a black body’s spectral radiance and its temperature. Basic Principle of Wien’s Displacement Law The law states that the…

Blackbody Radiation
Understanding Blackbody Radiation A black body in physics is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The radiation emitted by such a body, known as blackbody radiation, is a fundamental concept in quantum mechanics and thermodynamics. Blackbody Radiation Spectrum The radiation from a black body…
