UV radiation photons with a wavelength of 3.45 ? 10^−7 ? are incident on a metal surface in a vacuum. Photoelectric effect took place and electrons were instantaneously emitted from the surface with a maximum kinetic energy of 1.52 eV (electron-volt is another unit for energy, where 1 eV = 1.602 ? 10^−19?). What is the Work Function of the unknown metal?
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.
