When ultraviolet light with a wavelength of 264 nmnm falls upon a clean metal surface, the stopping potential necessary to terminate the emission of photoelectrons is 0.178 VV . A) What is the photoelectric threshold wavelength for this metal? Express your answer in nanometers. B) What is the work function for the metal? Express your answer in electronvolts.
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.
