3.2.
Fermat's Principle and Refracting Surfaces
31
We now apply these results in turn to optical surfaces separating homogeneous
media, such as air and glass, and to one inhomogeneous medium, the Earth's
atmosphere.
3.2.
FERMAT'S PRINCIPLE AND REFRACTING SURFACES
In this section we consider several examples of refracting surfaces and
approach them from the point of view of Fermat's Principle. In doing this we
will rederive some of
the
results of Chapter 2 as well as find some new ones. For
all of
the
cases discussed we assume that homogeneous media are separated by a
surface across which the index changes abruptly.
