A jumble of wavelengths

Figure 4.1 presented an oversimplified view that will make it easy to understand idealized lenses in Section 4.2. Unfortunately, it misses many details that become important in other settings, such as understanding lens aberrations (Section 4.3) or how light interacts with materials in the physical world. The remainder of this section therefore considers various realistic complications that arise.
