The stopping potential for photoelectrons emitted from a surface illuminated by light of wavelength λ1 = 491nm is V1. When the incident wavelength is changed to a new value λ2 = 382nm, the stopping potential is doubled. a) What is the numerical value of V1? b) What is the work function for the surface?
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.
