The frequency and the intensity of a beam of light falling on the surface of a photoelectric material are increased by a factor of two. This will:
- increase the maximum kinetic energy of photo electrons, as well as photoelectric current by a factor of two
- increase the maximum kinetic energy of the photo-electron and would increase the photoelectric current by a factor of two
- increase the maximum kinetic energy of the photo electrons by a factor of two and will have no effect on the magnitude of the photo-electric current
- not produce any effect on the kinetic energy of the emitted electrons but will increase the photoelectric current by a factor of two
Answer
(D) not produce any effect on the kinetic energy of the emitted electrons but will increase the photoelectric current by a factor of two
