I shine light of wavelength 260 nm on a photoelectric metal whose cut-off frequency is 5.6*1014 Hz. What is the kinetic energy of the most energetic photoelectron that are emitted? a. 1.5 eV b. 2.5 eV c. 3.5 eV d. none of these
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.
