A photoelectric experiment has a work function = 6.35 eV. The minimum cutoff frequency is 1.53E15 Hz a.) Purple light (wavelength 420 nm)- the energy of the photon is ______ eV What is the kinetic energy? b.) Ultraviolet (wavelength 130 nm)- the energy of the UV photon is _______eV. What is the kinetic energy?
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.
