Answer to relevant QuestionsIn Compton scattering, if the photon is scattered at a angle, in which direction will the electron recoil? Why? Is 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? (a) Compared with a quantum of red light , a quantum of violet light has (1) more, (2) the same amount of, (3) less energy. Why? (b) Determine the ratio of the photon energy associated with violet light to that related to ...The work function of metal A is less than that of metal B. (a) The threshold wavelength for metal A is (1) shorter than, (2) the same as, (3) longer than that of metal B. Why? (b) If the threshold wavelength for metal B is ...When the wavelength shift for Compton scattering from a free electron is a maximum, what is the scattering angle?
