How does the quantum theory of atoms explain the nature of the emission-line spectrum of hydrogen?

Energy takes on discreet values, we notice that only certain values of energy are allowed hence the line spectrum of the hydrogen atom.

According to the Bohr model of the atom, energy levels within the atom is quantized. Energy quantization implies that energy occurs in discreet packets and do not take on intermediate values.

Because energy takes on discreet values, we notice that only certain values of energy are allowed hence the line spectrum of the hydrogen atom.
