The walls of a blackbody cavity are at a temperature of 20oC. What is the wavelength of the radiation of maxi-mum intensity?
Answer to relevant QuestionsThe 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. When light of wavelength of 200 nm is incident on a surface, the maximum kinetic energy of the photo-electrons is measured to be 6.0 x 10-19. What is the work function of the surface? The photoelectric effect threshold wavelength for a certain metal is 400 nm. Calculate the maximum speed of photoelectrons if we use light having a wavelength of (a) 300 nm, (b) 400 nm, and (c) 500 nm. What are the wavelength and frequency of the most intense radiation component from a blackbody with a temperature of 0oC? Find the radius of the electron orbit in a hydrogen atom for states with the following principal quantum numbers: (a) n = 2, (b) n = 4, (c) n = 5.
