(a) The energy needed to extract an electron from sodium is 2.3 eV. Would sodium exhibit a photoelectric effect with orange light of λ = 680nm? (b) A photon beam is incident on a metallic sodium surface, whose work function is E0 = 2.2 eV , producing a photoelectron emission. When a retarding potential V0 = 5V is applied, the photocurrent disappears. What is the λ of the incident photons? What region of the spectrum does it belong to?
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.
