spectrometers split light, then the spectral lines show , and you can use spectral analysis to find out what elements are making the light.
The Maximum spectral response of the germanium and silicon is in the x-ray region
The photosphere of the sun doesn't really produce a continuous spectrum; there are discontinuities corresponding to energy levels of various chemical elements, called spectral lines. Notably Helium was discovered in the absorption lines of the solar spectrum and only later discovered on Earth.

... a photonic 'fingerprint'. The picture of a star's spectral lines is its photo-spectrograph.
An optical instrument that consists of an entrance slit, collimator, disperser, camera, and detector and that produces and records a spectrum. A spectrograph is used to extract a variety of information about the conditions that exist where light originates and along the paths of light. It reveals the details that are stored in the light's spectral distribution, whether this light is from a source in the laboratory or a quasistellar object a billion light-years away.For the source and more detailed information concerning this issue, click on the related links section below.
To read a spectrograph, interpret the x-axis as frequency or wavelength, the y-axis as intensity, and the colors or patterns as different spectral lines corresponding to different elements or compounds. Peaks or dips in intensity indicate the presence of specific emissions or absorptions at certain frequencies or wavelengths.

One use of light spectra has an application in astronomy. When looking at distant objects like galaxies, you can tell if they are moving away from you or closer to you. If the spectral light appears blue (blue-shift) it means that the object is moving toward you, if the spectral light is red (red-shift) it means that the object is moving away from you. Another astronomy application is to look at the light from a star through a spectrum and by doing so you can figure out the chemical composition of the star just by the color of its spectrum.
