An isolated copper sphere of radius 85.9cm is initially uncharged. It is illuminated by ultraviolet light of wavelength 174.6nm. What charge (C) will the photoelectric effect induce on the sphere? The work function of copper is 4.7eV.
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.
