A student studying the photoelectric effect from two different metals notices that metal 1 has a stopping potential 2.17V2.17V higher than metal 2 for all frequencies of incident light above the cut-off frequency of metal 2. The student also notices that the cut-off frequency of metal 1 is 50% of the cut-off frequency of metal 2. What is the cut-off frequency of metal 1, in eV? and of metal 2, in eV?
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.
