...EADIANT HEAT. When radiant heat is reflected it obeys precisely the same laws as light or sound, for the angle of incidence is always equal to the angle of reflection (p. 439). Thus it would appear that there is some reason as well as convenience in having a huge tin... | |

...That 'sa singular incident,' he thought to himself as he prepared to jump in. ' But hold a minute ! The angle of incidence is always equal to the angle of reflection. Upon reflection I find that the other dog and the meat are only optical phenomena.' And he trotted... | |

...P' that it makes with the normal is called the angle of reflection. It is a general law of physics that the angle of incidence is always equal to the angle of reflection; that is, NO P = NOP'. It follows that the angles PO .1 and P' OB are also equal. 17. Description of... | |

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...
