Question
Scientists have confirmed with emission spectra that the primary material of the sun are the elements
Hydrogen and Helium. However, the same scientists have also determined the material composition of
other stars that are not the sun and found those stars contain hydrogen, helium, lithium and beryllium. In
your own words, describe how the emission spectra can be used to confirm the materials that make up
stars?
Please only answer this above, Thank you!

Emission spectra can be used to confirm the materials that make up stars by analyzing the specific wavelengths of light that are emitted or absorbed by different elements. When a star's light passes through its outer layers or is emitted by its core, it can create a spectrum that shows bright lines at particular wavelengths. Each element emits light at unique wavelengths, which act like a fingerprint for that element.
By observing the emission spectrum of a star using spectroscopy, scientists can identify these distinct lines and match them to known wavelengths produced by various elements in laboratory settings. For example, if the spectrum of a star shows prominent lines corresponding to hydrogen and helium, scientists can determine that these elements are present in the star. In cases where additional lines appear that correspond to lithium or beryllium, it suggests that these elements are also part of the star's composition. Thus, emission spectra serve as a powerful tool for identifying the elements that comprise stars based on their unique spectral signatures.
