JC-21) Planck's Constant from Data When sodium metal is illuminated with light of wavelength is changed to 4.20 x 102 nm, the stopping potential is 0.65 V. When the wavelength is changed to 3.10 x 102 nm, the stopping potential is 1.69 V. Using ONLY THESE DATA and the values of the speed of light and the electric charge, find the work function of sodium and a value of Planck's constant.

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.
