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)
