The work function for platinum metal is 5.64 eV. In a photoelectric effect experiment, platinum is illuminated with monochromatic UV light of unknown wavelength. It is found that no current flows when the retarding potential becomes more negative than 1.06 V. (a) Deterimine the wavelength of illumination above which no photoelectrons are emitted for this metal. (b) Calculate the wavelength of UV light that corresponds to the measured stopping potential. Assume the photon intensity is constant.
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.
