005-ALEVEL PHYSICS PAPER 1 | THERMAL RADIATION (BLACK BODY RADIATION) | FOR SENIOR 5 & 6

In this video I take you through the calculations on the topic of thermal radiation. This involves calculations on: -Wein’s displacement law. -Stefan’s law. -Heat exchange for a black body in an enclosure. -Emissivity of a black body. -Emission and absorption of heat by planets in the universe. -Total power radiated by the sun. -Temperature of the sun. -Energy intensity of the sun. -Rate of loss of mass by the sun. -Prevost’s theory of heat exchanges. -Power received by the planet. -Temperature of the planet. The video contains numerous worked examples from UNEB Question Bank; and is suitable to A-level students in Senior Five and Six offering Physics as part of their combination. E.g. (PCB, PCM, PEM, PMT, PMA, e.t.c)
