...Caustic Curves, the rays of light being regarded as parallel, and the law of reflexion of light being that the incident and reflected rays make equal angles with the normal, at the point of incidence. For a detailed investigation of these curves, see the Analysis of the Marquis... | |

...SB, parallel to KT, and B, its intersection with the plane TP, will evidently be the point at which the incident and reflected rays make equal angles with the normal to the plane. Hence B is the brilliant point required. Remarks.—a. Observe, that as NT is normal to the... | |

...2. Regular Reflection.—A ray incident on a smooth surface is partly transmitted, partly reflected; the incident and reflected rays make equal angles with the normal to the surface (see diagrams, fig. 1). The intensity of the reflected ray increases rapidly with the angle... | |

...When light is reflected from a smooth surface, it obeys the well-known law of reflection, which states that the incident and reflected rays make equal angles with the normal to the surface and that both rays and the normal lie in one plane. When light is transmitted, the ray direction... | |
