a) In an experiment to investigate the photoelectric effect, a metal surface is illuminated with monochromatic light and photoelectrons are emitted. If the experiment were repeated with light of the same frequency but twice the intensity, state what effect, if any, this would have on the photon energy, and the maximum kinetic energy of the photoelectrons emitted. b) A certain metal surface has a work function of 0.66 eV. Calculate the value of the work function in joules. (e = 1.6 x 10-19 C), as well as, the maximum kinetic energy of the photoelectrons emitted when the surface is illuminated with light of wavelength 520 nm. (h = 6.6 x 10-34 Js, c = 3.0 x 108 m s-1)
Compton effect
The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.
Recoil Velocity
The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.
