The region of the spectrum is the visible spectrum.
Explanation:
- An electron jumps from an excited state to a ground state in the hydrogen atom.
- A hydrogen atom has only one electron in its outermost shell.
- Therefore, for ground state n = 1
- For excited state n = 2
- When it jumps from higher to lower state the amount of energy emitted is 10.2eV
- The corresponding transition of electrons is from the Lyman series.
