...angular deflection. The degree of angular deflection is described by the first mirror law, which states that the angle of incidence is always equal to the angle of reflection. The angular path of a reflected ray in spherical space is described by the second mirror law, which... | |

...light strikes a plane mirror, or the planar boundary between two media of different refractive index, the angle of incidence is always equal to the angle of reflection, as shown in Fig. (14.2). This is the fundamental law of reflection. When a light ray crosses the boundary... | |

...conclusion—a false perceptual conclusion in this case; see II,22, n. 32 below. 15 That is, in reflection the angle of incidence is always equal to the angle of reflection. Evidently, Ptolemy thought that the basic form of curved mirror was spherical rather than circular;... | |

...and the normal is called the angle of reflection (Lr). Whenever a pulse is reflected, it is observed that the angle of incidence is always equal to the angle of reflection. This is called the Law of Reflection Li = Lr. Figure 23 shows two examples of straight pulses being... | |

...hands behind your ears to collect sound waves). The Law of Reflection (the Help Sheet is needed here) The angle of incidence is always equal to the angle of reflection. (This almost applies also to balls bouncing but is slightly changed by friction at the surface; you... | |

...incidence. The angle which the reflected ray makes with its normal is called the angle of reflection. The angle of incidence is always equal to the angle of reflection. Thus, the direction of the ray of light is measured by the angle it makes with the normal (perpendicular... | |

...only be seen by looking into the mirror. The law of reflection states that wherever reflection occurs, the angle of incidence is always equal to the angle of reflection. When light rays strike objects their frequencies match either an allowable electron transition or molecular... | |

The disciples of Plato contributed not a little to the advancement of optics, by the important discovery they made, that light emits itself in straight lines, and that the angle of incidence is always equal to the angle of reflection. Plato terms colours...
