The Straight and Narrow Path of Waves

Part of the Lecture Notes in Physics book series (LNP, volume 895)


The unification of electricity and magnetism through Maxwell’s equations led to our understanding of light as an electromagnetic wave. This historical milestone allowed us to think of light as made of oscillating electric and magnetic fields, each of which obeys a wave equation. In this chapter we want to look at the wave nature of light from a particular point of view [66] which we will connect up with a seemingly different phenomenon in Chapter  17.
