Emission Spectra

Emission spectra are the unique patterns of light emitted by atoms or molecules when their electrons move from higher to lower energy levels. When an energy source excites the atoms, electrons jump to higher states; as they return to their original levels, they release specific wavelengths of light. These wavelengths appear as distinct lines, creating an emission spectrum. Each element has a characteristic spectrum, acting like a fingerprint, which scientists can analyze to identify substances or understand their properties. This process is fundamental in fields like astronomy, chemistry, and physics for studying the composition of distant stars, gases, and various materials.
