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.
Answer to relevant QuestionsA photon can undergo Compton scattering from either an electron or a neutron. How does the maximum wave-length shift for Compton scattering from a neutron com-pare with that from an electron? Explain. (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 ...Find the approximate temperature of a red star that emits light with a wavelength of maximum emission of 700 nm (deep red). When a certain photoelectric material is illuminated with red light (λ = 700 nm) and then blue light (λ = 400 nm), it is found that the maximum kinetic energy of the photoelectrons resulting from the blue light is twice ...X-rays of frequency 1.210 x 1018 Hz are scattered from electrons in an aluminum foil. The frequency of the scattered X-rays is 1.203 z 1018 Hz. (a) What is the scattering angle? (b) What is the recoiling speed of the ...
