An electron in H -atoms jumps from some higher level to 3rd energy level.If three spectral lines are possible for the transition, find the initial position of electron.

Explanation

To solve the problem of determining the initial position of an electron in a hydrogen atom that transitions to the 3rd energy level and produces three spectral lines, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Energy Levels**:
In a hydrogen atom, the energy levels are quantized and denoted by the principal quantum number \( n \). The possible values of \( n \) are 1, 2, 3, 4, 5, and so on. The electron can jump from a higher energy level to a lower energy level, emitting a photon in the process.

2. **Identifying the Final Energy Level**:
