Dear aspirant,
When an electron transitions from the fifth orbit to the ground state in a hydrogen atom, a total of 10 spectral lines can be observed. This is because the electron can make transitions to any lower energy level, including directly to the ground state (n=1), or to intermediate levels (n=2, 3, or 4) before reaching the ground state.
