Ray optics and optical … WebIn the case of a reflected ray, nA = nB = n2 = n1, n1 Sinθ i = n1 Sinθ r, which is the same as Sinθ i = Sinθ r. From this, it is easy to see that the angle of incidence and the angle of reflection are the same! In the case of the transmitted, or refracted, ray, n1 Sinθ i = n2 Sinθ t. Snell's law can be derived in various ways. Snell's law can be derived from Fermat's principle, which states that the light travels the path which takes the least time. By taking the derivative of the optical path length, the stationary point is found giving the path taken by the light.

WebR r = R i - 2 N (R i . N) Some obvious things to note at extreme cases. If R i is parallel to the normal then R r = N, that is, the reflected ray is in the opposite direction to the incident ray. If the incident ray is perpendicular to the normal then it is unaffected, R r = R i, this is a glancing ray. Note also that while the above diagram is ... Webwhich the refracted arrival overtakes the direct arrival can be used to determine the layer depth.
