Studying Fraunhofer lines helps to identify elements on the stars.

The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star.

================================

Fraunhofer's spectral lines.

Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.

hahaha boang ka cm8 oi.. kinsa ka? naka answer naka?
