5. In instrumental analysis, various methods are employed, including chromatography, electrochemistry, spectroscopy, and many others. Spectroscopy involves the study of the interaction between matter and electromagnetic radiation. It provides valuable information about the composition, structure, and properties of substances. (a.) Please describe the basic principle of spectroscopic chemical analysis (Hint: You may need to draw the picture) (b.) (Bonus Challenge) According to the interaction between electromagnetic radiation with substance. There are three kinds of spectra: Absorption, Emission and Fluorescence. You have already known the Absorption. Please preview the part of Emission and Fluorescence part in your Textbook, and then try to compare them. For example, (b-1.) Like 4-(a.), please draw the general form of the instruments. (b-2.) Compare and explain the change in wavelength between the incident and detected radiation shown in each spectrum if a monochromatic incident radiation is used
