Transition between three energy energy levels in a particular atom give rise to three Spectral line of wevelength , in increasing magnitudes. `lambda_(1), lambda_(2)` and `lambda_(3)`. Which one of the following equations correctly ralates `lambda_(1), lambda_(2)` and `lambda_(3)`?

Explanation

To solve the problem regarding the relationship between the wavelengths of the spectral lines \( \lambda_1 \), \( \lambda_2 \), and \( \lambda_3 \), we will follow these steps:

### Step 1: Understand the Energy Levels
We have three energy levels in an atom, which we can denote as \( E_1 \), \( E_2 \), and \( E_3 \). The transitions between these energy levels give rise to the spectral lines with wavelengths \( \lambda_1 \), \( \lambda_2 \), and \( \lambda_3 \).

### Step 2: Establish the Order of Wavelengths
According to the problem, the wavelengths are in increasing order:
\[
