Interpretation:
Hydrogen atom having the desecrate energy levels, reason behind which is to be explained and the way in which this fact reflected in the radiation that excited hydrogen atoms emit also needs to be explained.
Concept introduction:
The desecrate energy levels means each energy level has a definite amount of energy.

Answer to Problem 14A
Hydrogen atom has discrete energy levels means that the electron are occupy only in some specific orbits which having a specific energy. So, some specific colors of light are emitted by the excited hydrogen atom. Electronsjump from one energy level to other energy level with the removal or absorption of the photos which possess energy equal to the energy difference between these energy levels.
Explanation of Solution
According to Niels Bohr’s theory hydrogen atom has desecrate energy levels because electrons are revolve around the nucleus in specific orbits which having the specific amount of energy. Each orbital has different amount of energy. The orbits are quantized. So, due to some specificorbits only specific colors of light are emitted by the excited hydrogen atom. When an electron jumps from one energy level to other energy level with the removal or absorption of the photons which possess energy equal to the energy difference between these energy levels.
Due to the revolution of electrons in specific orbits with the specific energies, some specific colors of light are emitted by the excited hydrogen atom.
