Question 21 5 pts Imagine you attach a spectrograph to your telescope, and you take the light from a distant astronomical object and spread it out into a spectrum. You notice that the spectrum looks strange, with narrow dark lines of various colors that seem to be "missing". Why is this actually helpful to you, rather than being a problem? The wavelengths of the missing colors tell you which chemical elements (ie, types of atoms) the object is made of The fact that certain colors are missing' from the spectrum tells you that the atoms in the distant object are missing certain electrons from their atomic structures. The fact that some of the colors in the spectrum are 'missing' is a sign that these atoms contain electrons that are transforming into protons, and vice-versa. The wavelengths of the missing' colors tell you which chemical elements are definitely not present in the object
