The grond state energy of hydrogen atom is ` 13.6 eV`. If an electron makes a transition
from an energy level - 1.51 eV to - 3.4 e V , calculate the wevelength of the spectrel line
emitted and name the series of hydrogen spectrum to which it belongs.

Explanation

To solve the problem of calculating the wavelength of the spectral line emitted during the transition of an electron in a hydrogen atom, we will follow these steps:

### Step 1: Identify the Energy Levels
We are given two energy levels:
- Initial energy level (E_initial) = -1.51 eV
- Final energy level (E_final) = -3.4 eV

### Step 2: Calculate the Energy of the Transition
