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?
Answer to relevant QuestionsWhen 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 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 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 wavelength 0.01520 nm are scattered from a carbon atom. The wavelength shift is measured to be 0.000326 nm. (a) What is the scattering angle? (b) How much energy, in eV, does each photon impart to each electron? What is the frequency of light that would excite the electron of a hydrogen atom (a) From a state with a principal quantum number of n = 2 to that with a principal quantum number of n = 5? (b) What about from n = q to n = ...
