The positions of the peaks and dips in the spectrum of an object provide evidence about its elemental composition. Each element has a unique set of energy levels, and when light passes through or is emitted by an object, it interacts with the electrons in the atoms of that object. This interaction leads to absorption or emission of specific wavelengths of light, resulting in peaks and dips in the spectrum. By analyzing the positions and intensities of these peaks and dips, scientists can determine the presence and relative abundance of different elements in the object.
