In a photoelectric effect experiment, light with a frequency of 8.85E14 Hz is shone on a clean metal surface. The work function of the metal is 1.87 eV. What is the initial kinetic energy of an electron emitted from the metal surface (in eV; answer 0 if no electron is emitted)?
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.
