How many spectrual lines are emitted by atomic Hydrogen, when an electron jumps from 5th energy level to ground state ?

Explanation

To determine how many spectral lines are emitted by atomic hydrogen when an electron jumps from the 5th energy level (n=5) to the ground state (n=1), we can use the formula for calculating the number of spectral lines emitted during such transitions.

### Step-by-Step Solution:

1. **Identify the Energy Levels:**
- The initial energy level (n2) is 5 (the level from which the electron is jumping).
- The final energy level (n1) is 1 (the ground state).
