Far ultraviolet light with a wavelength of 154 nm is incident on an unknown solid surface, which releases photoelectrons with a maximum speed of 8.10 ✕ 105 m/s. (a) What is the work function of the unknown solid? eV (b) What is the minimum frequency of incident light for which photoelectrons will be released from this surface? Hz
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.
