Interpretation Introduction

**Interpretation:**

The wavelengths in the increasing order of the first four transitions in the Balmer series of the *Rydberg equation* in them.

**Concept Introduction:**

**Absorption** refers to how much light can be taken in by the material being measured.

When electromagnetic radiation interacts with matter, atoms and molecules may absorb energy and reach to a higher energy state. With higher energy, these are in an unstable state. For returning to their normal (more stable, lower energy) energy state, the atoms and molecules emit radiations in various regions of the electromagnetic spectrum. The spectrum of radiation emitted by a substance that has absorbed energy is called an **emission spectrum**.

In 1885, Johann Balmer developed a simple equation which could be used to calculate the wavelengths of the four visible lines in the emission spectrum of hydrogen. Johannes Rydberg developed Balmer’s equation further, giving an equation which could calculate the *visible* wavelengths and also those of *all* hydrogen’s spectral lines.

This equation is known as the ** Rydberg equation**. Here,

**To find:** Calculate the wavelengths in the increasing order of the first four transitions in the Balmer series of the
