. i. Calculate the maximum wavelength λmax of electromagnetic radiation that could eject electrons from the surface of platinum with a work function of 9.50x10−19 J. ii. If the max speed of the emitted electrons is 3.65x106 m/s, what wavelength of electromagnetic radiation struck the surface and caused ejection of the photoelectrons? Use an electron mass of 9.11x10−31 kg if needed.
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.
