3. Determine the index of refraction at the two extremes of the visible spectrum. Add an appropriate vertical scale to the graph below and plot these two data points. Although the shape of the function is not known to us, with a freehand flourish pencil in the trend (upward or downward) on the graph. (Rhetorical: What atomic or molecular scale properties of a material cause the index of refraction to depend on wavelength?)
