Reflection and Refraction of Light

The most prominent optical properties of surfaces and interfaces which we face in our everyday life are represented by the reflection and refraction of light. These phenomena occur at all boundaries between different media and due to them we can identify objects or are able to use various optical devices. The human sight itself is possible due to refraction of light in the eye. The laws that govern these phenomena were first derived by Fresnel in 1823.

The Fresnel laws of reflection and refraction of light in nondissipative media have been known for over 180 years. However, these laws do not apply to the total reflection of an incident wave at the boundary between a dissipative medium and a vacuum region [26]. 

At each interface, reflection and refraction of the acoustic energy occur similar to the reflection and refraction of light at the boundary between two materials of different optical densities (see Chapter 9).

Ford and Wheelerin their semiclassical treatment of quantum mechanical rainbow scattering remark that the necessary mathematics is not essentially different from Airy s treatment of the reflection and refraction of light. Indeed, their semiclassical formula for the cross section contains the Airy function or rainbow integral. The semiclassical cross section is illustrated schematically in Fig. 3c. The supernumerary rainbows of the wave mechanical theory are clearly resolved in the Na-Hg cross section measurements of Buck and Pauly, reproduced here in Fig. 5.
