Ejection of electrons from hydrogen by incident photons light of wavelength 80 nm is incident on a sample of hydrogen gas, resulting in electrons being ejected from the atoms. n. b. the energy of these photons is much smaller than the rest energy of the electron, so you don't need relativistic expressions. assume that the photon is destroyed in this process, leaving only the electron moving away from a stationary hydrogen ion.
a. with the gas in thermal equilibrium at room temperature, what would be the maximum kinetic energy of ejected electrons?
b. when an intense light source of the same wavelength is shone on the gas sample, a small number of electrons with kinetic energy as much as 10.2 ev greater than you calculated in part a. explain how this can be.
