An electron jumps from fourth to first orbit in an atom. How many maximum number of spectral lines can be emitted by the atom ?

Explanation

To determine the maximum number of spectral lines emitted when an electron jumps from the fourth to the first orbit in an atom, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Orbits**:
- The electron is initially in the fourth orbit (n = 4) and jumps to the first orbit (n = 1).

2. **Understand Spectral Lines**:
