Question: The Sun s energy production near its center is initially in
The Sun’s energy production (near its center) is initially in the form of X-rays and gamma rays. By the time it reaches the surface, it is mostly in the visible range. Use Compton scattering to explain how this happens.
Relevant QuestionsThe walls of a blackbody cavity are at a temperature of 20oC. What is the wavelength of the radiation of maxi-mum intensity? The work function of a surface is 5.0 x 10-19 J. If light of wavelength of 300 nm is incident on the surface, what is the maximum kinetic energy of the photoelectrons ejected from the surface? Figure 27.21 shows a graph of stopping potential versus frequency for a photoelectric material. Determine (a) Planck’s constant and (b) The work function of the material from the data contained in the graph. When the wavelength shift for Compton scattering from a free electron is a maximum, what is the scattering angle? Find the energy of a hydrogen atom whose electron is in the (a) n = 2 state and (b) n = 3 state.
