This technique can and will be used by us to look at a variety of pigments in egg tempera paints when we make color wheels in our class-wide experiment. Chemists can use this technique as a way of determining which compounds are present, as a way of investigating the structure of compounds that are present, or as a means to determine how much of a particular compound is present. Here we will pay particular attention to the wavelengths of light that have been removed from the overall spectrum by interaction with matter. Look briefly at spectroscopy, a means of looking at the variations of intensities in light of different wavelengths across the whole spectrum of visible light.

Give one color while a second compound generates another color. Theory and then use this knowledge to explore why one chemical compound will For the purposes of this class we will look first at color Is useful for artists to understand how colors are formed as well as how theyĪre perceived. Color is one of the principle elements of the visual arts.
