Question
HELP!!! Here is a graph I made, and im being asked to explain the trends in the dips and waves. The exact question being asked is as follows: Explain the dips and peaks you see for each of the primary colors.
I dont understand the relationship between color, absorbtion, and wavelength - can someone explain this to me?
Also, the color of the solution mixture used during the experiement is labeled in the graphs key. We are also being asked; explain how each mixture corresponds to the primary colors that were used to make it. Does this mean that their is a difference in the color of the solution used and the trends (that ultimately determine what color would be visible) that are present on the graph?

In the above absorption versus wavelength graph, the dips are known to be due to absorption and thus are referred to as the absorption lines. Broader is the curve (wave) lower would be the absoprtion line. Color is related to absorption or emission. The more intense a color is the lower would be the wavelength of it, E = hc/lambda; So as move from 440 nm to the 740 nm region, the color becomes less intense and thus of lower energy. So a red light would have the longest wavelength (lowest energy) whereas, a violet has the shortest wavelength (highest energy). The color becomes more intense as the light of shortest wavelelngth is absorbed. so as one moves from shorter wavelengths to longer wavelenghts the color becomes lighter, and more visible. The color which is seen to the eye is due the emission wavelength. When light of certain wavelenght is absorbed, it would emit the reamining portion of light and this is what is seen as the color to the maked eye. There is definite regions for the three colors used as primary colors which overlaps with the other secondary colors in the absorption spectrum. The Red, blue and the yellow (not shown here) regions. Exach primary color region consists of several other secondary colors, which when comes together gives a set of new colors and thus are used as primary colors.
