Interpretation:
This is to be explained how the Bohr’s theory accounts for the emission of discrete
Concept introduction:
The energy of emitted light is equal to the difference in energy between electrons in different orbits.

Answer to Problem 19A
The fact in which Bohr’s theory accounts for the emission of discrete wavelength of light by an excited atom is explain by describing the energy of light emitted being equal to the energy difference between the electrons in different orbits.
Explanation of Solution
The lowest energy state is the ground state of the atom which is most stable state. A transition line is introduced when an electron is going form excited state to ground state with the emission of light with the finite number of wavelength only. So, There is a certain number of wavelength is observed corresponding to each transition line.
Thus, one say that the Bohr’s theory accounts for the emission of discrete wavelength of light by an excited atom by describing the energy of light emitted.
