he minimum wavelength of electromagnetic radiation that is capable of removing electrons from the surface of barium metal is 693 nm. i. Calculate the work function for barium metal in kilojoules per mole of electrons ejected. If a light source with a frequency of 3.75x10^14 s‒1 is directed at the surface of barium metal, what will be the maximum kinetic energy of the ejected electron
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.
