maximum wavelength of incident light that releases photoelectrons from the surface of a platinum sample is 195 nm. Calculate: The cutoff frequency for platinum: The work function for platinum in eV: The minimum energy required to release photoelectrons from the platinum surface: The maximum kinetic energy of the ejected photoelectrons, in eV, if the incident photons’ wavelength is 124 nm:
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.
