Question

Photoelectron spectra were acquired from a sample of gaseous N₂ using a light source with an energy of 21.22 eV (1 eV = 1.602 x 10^-19 J). Photoelectrons were detected with velocities of 1.407 x 10⁶ m s^-1 and 1.262 x 10⁶ m s^-1. Calculate the ionization energies represented by these velocities of electrons.
