Chapter Nine RAY OPTICS AND OPTICAL INSTRUMENTS
Physics 312 The distance between the focus F and the pole P of the mirror is called the focal length of the mirror, denoted by f.We now show that f = R/2, where R is the radius of curvature of the mirror. The geometry of reflection of an incident ray is shown in Fig. 9.4.

Now, if we know the shape of the wavefront at t = 0, then Huygens principle allows us to determine the shape of the wavefront at a later time τ. Thus, Huygens principle is essentially a geometrical construction,
