Abstract

This laboratory exercise is an introduction to spectrophotometry suitable for college freshmen and high school students. It involves food dyes and brown M ;candy. The spectra of "primary" dyes are measured and represented graphically as absorbance vs wavelength to show that minimum absorption of light occurs in the spectral region corresponding to the color of the dye.
