Recall that ray paths are normal to a geometrical wavefront (ie, an eikonal surface), which means that all rays converging to a point (say, to Q 0 in Fig. 3.22 ) must correspond to a spherical …

A line segment is something that has a start and an end (2 endpoints)-so basically the opposite of a line. Then a ray is something with a starting point, but no end. So a ray is like a line, but only one part is endless. greenhead gun clubWebwave front, also called wavefront, imaginary surface representing corresponding points of a wave that vibrate in unison.
