What determines the maximum kinetic energy of the electron emitted from the photosensitive plate?
smoothness of plate
frequency of incident light and work function of plate both
work function of the plate
frequency of incident light
The frequency of incident light falling on a photosensitive metal plate is doubled, the kinetic energy of the emitted photoelectrons is
