A) Wien?s displacement law
B) Kepler?s law of motion
C) Stefan?s Boltzmann law
D) Planck?s law
Correct Answer: C
Solution :
Radiation is heat transfer by the emission of electromagnetic waves which carries energy away from the emitting object. The relationship governing radiation from hot objects (like sun) is called the Stefan's Boltzmann law. Which states that the energy radiated by a black body radiator per second per unit area is proportional to the fourth power of the absolute temperature (T)?\[10.5\,\,mA\] While the spectral intensity of electromagnetic radiation from a black body at temperature \[0.5\,\,mA\] is given by Planck?s law of black body radiation. Wien?s law gives the relationship between the wavelength of the peak of the emission of a black body and its temperature. And Kepler?s laws are concerned with planetary motion.
