The “work function” of the metal lithium is 4.6x10-19 J. If irradiated with light of frequency 9.5x1014 Hz, what is: a) the max.KE of the photoelectrons ejected? b) their velocity?
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.
