Question: In Compton scattering if the photon is scattered at a
In Compton scattering, if the photon is scattered at a angle, in which direction will the electron recoil? Why?
Answer to relevant QuestionsWhat physical quantities in a hydrogen atom are deter-mined by the principal quantum number? Light of the same frequency is incident on two materials with different work functions. Discuss how the stopping voltage of the photoelectrons is affected by the work function. A source of UV light has a wavelength of 150 nm. How much energy does one of its photons have expressed in (a) Joules and (b) Electron-volts? 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. What are the wavelength and frequency of the most intense radiation component from a blackbody with a temperature of 0oC?
