Review Set 3 (con’t)
1. Given the color wheel, what color do you see? Why?
2. Roughly, what is the visible range of wavelengths? What colors do they correspond to?
3. What is Grassman’s law?
4. Define: Hue, Saturation and Luminosity.
5. Sketch the visible color Gamut in chromaticity coordinates x, y. Indicate the hue and
saturation directions.
6. What is a convex hull? What is the relationship between the visible Gamut, Grassmans
law and a convex hull?

a. In the graph above, what are the functions r() g() and b() called?
b. What is the color composition of a test light with a wavelength of 450nm? Roughly,
what color is the test light?
8. Why is Calvin Goddard important?
9. What happens to white light when it passes though a prisim? Why? Which
wavelengths are slowest (fastest)?
10. What is the principle difference for microscopy of solid materials vs transparent
materials?
11. What is the difference between an isotropic material vs and anisotropic (transparent)
material? What class are most materials?
12. What is light polarization and why is it important to microscopy?
