The phase functions of these solutions are lin-ear. CGO optics have been used in EIT and have been instrumental in solving several inverse problems. We will not review these devel-
In some sense, the point of these investigations has very little to do with optics, or even differential equations, per se. The point is to have students appreciate the many approaches available to them as they struggle with a realistic problem, to see both the value and the limitations of each of these approaches, and to see the way in which the various approaches interact.

GEOMETRICAL OPTICS FORMULAES FOR HELMHOLTZ EQUATION FRANC¸OIS CUVELIER Abstract.
If we consider a convex lens, a system of two plano-convex (planar on one side) lenses, we can use the formula that 1/f = 1/f 1 +1/f 2 to arrive at the lens-makers equation. By far the most important formula in geometrical optics, however, relates the position of an object placed in front of a lens to the position of its image, formed by the lens.
Geometrical optics deals with the propagation of light in a straight line and phenomena such as reflection, refraction, polarization, etc. A ray of light gives the direction of propagation of light. In the absence of an obstacle, the rays advance These papers, with the exception of On some Quaternion Equations connected with Fresnel's wave surface, are included in The Mathematical Papers of Sir William Rowan Hamilton, Volume I: Geometrical Optics, edited for the Royal Irish Academy by A. W. Conway and J. L. Synge, and published by Cambridge University Press in 1931.

The method of geometrical optics will not solve all problems that involve light. There are problems in which light must be treated as a wave with interference effects; this is called physical optics and is the subject of the experiment, Diffraction and Interference.
Other important optics topics include interference, polarization, and fiber optics. Among the topics carefully presented in the book are nonlinear geometric optics, the asymptotic analysis of short wavelength solutions, and nonlinear interaction of such waves. Studied in detail are the damping of waves, resonance, dispersive decay, and solutions to the compressible Euler equations with dense oscillations created by resonant interactions.

by representing the light as rays. A light ray from a source goes in a straight line through the air, but when it encounters a lens, prism, or mirror it bends or changes direction. Lens Prism Mirror Surface 0 is the object plane, Surface 1 is the convex surface of the lens, Surface 2 is the plano surface of the lens, and Surface 3 is the image plane (Figure 3). Remember that the curvature (C) is equivalent to 1 divided by the radius of curvature (R). 3.1 Geometrical Optics ECE 460 –Optical Imaging If the objects encountered by light are large compared to wavelength, the equations of propagation can be greatly simplified (λ 0) i.e. the wave‐phenomena (tti(scattering, it finterference, et)tc) are neglected Determine focal length and magnification given radius of curvature, distance of object and image.
