If you have a system with two levels of energy. Prove that the probabilities of absorption and emission stimulated by black body radiation are equal
Suppose someone is running a fever of 102.0° F (average being 98.6° F). How much more power (in Watts) does this person radiate than when this person is at normal human body temperature, assuming the fever causes no swelling or edema, or emaciation? Remember that for thermal radiators, intensity I = sigma T^4; where sigma is the Stefan-Boltzmann constant and T is temperature in Kelvins.
If the wavelength of an electron is 5.00 x 10-7 m, how fast is it moving? (b) If the electron has a speed equal to 1.00 x 107 m/s, what is its wavelength?
