SUMMARY
The discussion centers on determining the greatest wavelength of radiation capable of ionizing an unexcited hydrogen atom. The key formula involves equating the photon energy to the ground state energy of hydrogen, which is approximately 13.6 eV. The longest wavelength corresponds to the lowest photon energy, calculated using the equation E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is wavelength. Additionally, while multiphoton processes may allow for longer wavelengths, they typically involve intermediate excited states with very short lifetimes.
