Blackbody Radiation

Abstract

Learning Objectives (ILOs) Verify the fourth law of radiation. Generate Planck’s curves for Stefan–Boltzmann lamp at di erent temperatures and verify Wien’s law. Verify the inverse square law for electromagnetic (EM) radiation. Principle of Work By measuring the emitted radiation from a heated lament, as a function of the temperature of the lament, wavelength of the emitted radiation and the distance from the black body, we can verify the fourth law of radiation, generates Planck’s curves at a di erent temperature, and the inverse square law for EM radiation.
