Question: Make a graph showing how the wavelength of the most
Make a graph showing how the wavelength of the most intense radiation component of blackbody radiation varies with the body’s absolute temperature. By what ratio does λmax change (final/initial) if the body’s absolute temperature is tripled?
Answer to relevant QuestionsIs it more dangerous to stand in front of a beam of X-ray radiation with a very low intensity or a beam of red light with a much higher intensity? How does the photon model of light explain this apparent paradox? The wavelength at which the Sun emits its most intense light is about 550 nm. Assuming the Sun radiates as a perfect blackbody, estimate (a) Its surface temperature and (b) Its total emitted power. Assume that a 100-W light bulb gives off of its energy as visible light. How many photons of visible light are given off in 1.00 min? (Use an average visible wavelength of 550 nm.) Blue light with a wavelength of 420 nm is incident on a certain material and causes the emission of photoelectrons with a maximum kinetic energy of 1.00 x 10-19 J. (a) What is the stopping voltage? (b) What is the ...A photon with an energy of 5.0 keV is scattered by a free electron. (a) The recoiling electron could have an energy of (1) zero, (2) less than 5.0 keV, but not zero, (3) 5.0 keV. Why? (b) If the wavelength of the scattered ...
