In this chapter, we address how to describe superposition of two or more light waves. This
issue arises in Chapter 7 where we combine two waves at a beamsplitter as in Figure 7.1A,
or an innite number of waves in a Fabry–Perot interferometer in Section 7.5. The question
of superposition arises again in Chapter 8 when we integrate contributions to the eld in an
image over the pupil in Equation 8.32, and implicitly in geometric optics through Chapters 2
through 5, when we combine rays to form an image, the details of which we will address in
Chapter 12.
Because Maxwell’s equations are linear partial differential equations for the eld
