What Is Spectroscopy??

Spectroscopy is the study of the interaction between matter and radiated energy. It originated through the study of Visible Light spread out according to its wavelength by a prism. Later this idea was Expanded to include any interaction with radiative energy as a function of its wavelength or frequency. I found this really cool video on Spectroscopy that explained it pretty well! Well its actually really boring but it really gave me an idea about what it really is!
