問題詳情

34. In an experiment, different wavelengths of light, all able to eject photoelectrons, shine on a freshlyprepared (oxide-free) zinc surface. Which statement is true?
(A) The number of photoelectrons emitted per second is independent of the intensity of the light forall the different wavelengths.
(B) The number of photoelectrons emitted per second is directly proportional to the frequency forall the different wavelengths.
(C) The maximum kinetic energy of the photoelectrons has a linear relationship with the frequencyfor each wavelength present.
(D) The maximum kinetic energy of the photoelectrons emitted is directly proportional to thefrequency for each wavelength present.
(E) The maximum kinetic energy of the photoelectrons is proportional to the intensity of the lightand independent of the frequency.
