Which of the following could happen if a photon of energy 14.8 eV enters a hydrogen atom in the ground state?

Accepted Answer

The atom would be ionized, and an electron would be ejected with a kinetic energy of 1.2 eV

Answer

Two photons, of energy 10.2 eV and 4.6 eV, would be emitted.

Answer

An electron of energy 13.6 eV and a photon of energy 1.2 eV would be emitted.

Answer

Two photons, of energy 13.6 eV and 1.2 eV, would be emitted.
