Lecture
This lecture covers the phenomena of heat transport, focusing on the Planck law for black body radiation, Stefan's law, and the concept of grey bodies. The slides discuss the relationship between absorbed and incident power, the derivation of black body emission, and the significance of these laws in classical physics. The lecture also explores the emission characteristics of black bodies and their temperature dependence, emphasizing the maximum emission wavelength and the concept of total emittance. Additionally, it delves into the application of these principles to real-world scenarios, such as solar radiation and the behavior of different surfaces under varying temperatures.
