Spectroscopy is the study of dispersion of light into colors. Light acts like waves and it has properties too. There are two types of spectra: continuous and discrete. In continuous spectrum, light is composed of continuous colors while in discrete spectrum, light can be seen as bright or dark lines distinctively. More on spectroscopy in these slides.
