...reflects an entire image of the luminary ; but as the image can be seen only by reflected rays, and as the angle of reflection is always equal to the angle of incidence, the image for any point can be seen only in the reflected ray prolonged. 2. Objects seen by moonlight appear... | |

...invisible. Whatever the reflecting surface may be, and however obliquely the light may fall upon it, the angle of reflection is always equal to the angle of incidence. Thus IC, 1J C, being rays incident on the surface at C, they will be reflected into CS, C S', so that... | |

...object and its reflection is then observed, and half of that is taken as the angle of elevation, since the angle of reflection is always equal to the angle of incidence. To prevent agitation by the wind, the mercury is frequently covered by a roof of plate glass. The basin... | |

...of space; the balls, then, that strike this piece on the recess, according to the wellknown law that the angle of reflection is always equal to the angle of incidence, fly from side to side in the decreasing cavity till they reach the recess which conducts them out the... | |

...body, it is either reflected, refracted or absorbed. What is the angle of reflection always equal to? The angle of reflection is always equal to the angle of incidence. When rays of light pass from a rarer to a denser medium, as from air into water, what are they refracted... | |

...ray makes the same angle with the perpendicular to the surface that the incident ray does, — ie, the angle of reflection is always equal to the angle of incidence. 294 Fig. 79 enables us to determine the course of the refracted ray by construction on paper, as follows... | |

...whatever may be the form and nature of the reflecting body, and the colour and intensity of the light, the angle of reflection is always equal to the angle of incidence, and in the same normal plane. Under this law, the analysis of the effects produced by all kinds of... | |
