For example, in optics, usually refraction is allowed only at the surface of objects or at the interface of media, each of which is assumed to have uniform index of refraction.

Gradient index

[edit]

Section Technique implies that ray tracing, in physics, always allows for a gradual variation in the index of refraction. That is not true. For example, in optics, usually refraction is allowed only at the surface of objects or at the interface of media, each of which is assumed to have uniform index of refraction. In fact, that is the raison d'être for gradient-index optics.— Preceding unsigned comment added by 99.251.254.165 (talkcontribs) 15:13, 23 April 2008‎

Ray tracing in the atmosphere

[edit]

I added a link in the Section radio signals to an application in Computation of radiowave attenuation in the atmosphere.--Thuytnguyen48 (talk) 15:16, 18 October 2010 (UTC)[reply]
