WHAT IS SPECTROSCOPY?THE MOST IMPORTANT SCIENCE IN ALL OF SCIENCE Spectroscopy is the study of the interaction between matter and electromagnetic radiation —it converts all of physics into numbers. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength via a prism.Later the concept was expanded to include any interaction with radiative energy as a function of its wavelength or frequency. Spectroscopy is a fundamental exploratory tool in the fields of physics, chemistry, and astronomy. Important applications arise from biomedical spectroscopy in the areas of tissue analysis and medical imaging.
