...general what .happens in the refleftion of rays, to our eyes, arid this fole principfe, principle, that the angle of incidence is always equal to the angle of refle&ion, is the true foundation of all the myfteries of catoptrics. We are now to know in what manner... | |

...reflection; and if eca be the angle of incidence, deb will be the angle of reflection. This general law, that the angle of incidence is always equal to the angle of refefiion, is the foundation of all catoptries, and is fufncient for demonflrating all the phenomena... | |

...summer and at noon are direct ; but in winter and the morning they are oblique. But it is demonstrated that the angle of incidence is always equal to the angle of reflection. Reflections however at right angles, more compress the air, and on this account the air is more heated... | |

...вг. General Laws of REFLECTION. — 1. When a ray of light is reflected from a speculum of any form, the angle of incidence is always equal to the angle of reflection. This law obtains in the percussions of all kinds of bodies ; and consequently must do so in those of... | |

...an equal degree of obliquity on the other side. To express this very important law shortly, we say that " the angle of incidence is always equal to the angle of reflection." — According to this law, any irregular surface must break an echo ; and if the irregularity be very... | |

...it strikes the plate, is called the angle of Incidence ,• EDA, is the angle of reflection ; hence the angle of incidence is always equal to the angle of reflection. If the plate be not flat, the reflected rays are either dispersed or concentrated. Thus, if they strike... | |

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...
