Hydrogen atoms:
(a) What is the minimum kinetic energy in electron volts that an electron must have to be able to ionize a hydrogen
atom that is in its ground state (that is, remove the electron from being bound to the proton)?
(b) If electrons of energy 12.8 eV are incident on a gas of hydrogen atoms in their ground state, what are the energies of
the photons that can be emitted by the excited gas?
(c) If instead of electrons, photons of all energies between 0 and 12.8 eV are incident on a gas of hydrogen atoms in the
ground state, what are the energies at which the photons are absorbed?
