(a.) Define stopping potential. (b.) Use Einstein's photoelectric equation to explain why: (i.) for a particular metal, electrons are emitted only when the frequency of the incident radiation is greater than a certain value. (ii.) the maximum speed of the emitted electrons is independent on the intensity of the radiation.
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.
(a.) Define stopping potential.
(b.) Use Einstein's photoelectric equation to explain why:
(i.) for a particular metal, electrons are emitted only when the frequency of the incident
(ii.) the maximum speed of the emitted electrons is independent on the intensity of the radiation.
