Absorption spectrum is observed when a photon is observed and a electron
Jumps to a higher state. Controversy emission spectrum is observed when
electron comes to lower state emitting a photon
On considering all possible transition states, thus no. of observation
and emission lines will be same

Explanation:
Absorption Spectrum:
- In the absorption spectrum, when hydrogen-like atoms in ground state absorb photons of various energies, five dark lines are observed.
- These dark lines correspond to the energy levels at which the electrons are transitioning from lower to higher energy levels.
Emission Spectrum:
- In the emission spectrum, when these excited atoms return to lower energy levels, they emit photons of specific energies.
- Each dark line in the absorption spectrum corresponds to a bright line in the emission spectrum.
- Therefore, if there are five dark lines in the absorption spectrum, there will be five bright lines in the emission spectrum.
Number of Bright Lines:
- As mentioned above, each dark line in the absorption spectrum corresponds to a bright line in the emission spectrum.
- Therefore, the number of bright lines in the emission spectrum will be the same as the number of dark lines observed in the absorption spectrum.
- In this case, there are five dark lines observed in the absorption spectrum, so there will be 5 bright lines in the emission spectrum.
Therefore, the correct answer is option C) 15.
