The presence of Iron in the outer layers of the sun can be detected using the technique of spectrography.
Explanation:
When atoms or molecules of elements like Iron are present in the outer layers of the Sun, they absorb certain wavelengths of sunlight.
These absorbed wavelengths of light form distinct dark lines in the spectrum of the sunlight when observed with a spectrograph.
By studying these dark lines called absorption lines, we can determine the type of element that is absorbing these wavelengths because, different elements absorb different wavelengths of light.
This image shows the detection of molecular sodium in the atmosphere of an exoplanet using the same technique.
