...given ratio to each other. This amounts to the same thing with saying that, in the case before us, the sine of the angle of incidence is to the sine of the angle of refraction in a given ratio. This explanation of the law of refraction is so satisfactory, that it... | |

...and water to measure 12 in., and the sine of the angle of incidence 16 in^ it would follow that in water the sine of the angle of incidence is to the sine of the angle of refraction as l'336 to I, or as nearly as possible i| to I. The number i'336, which expresses this ratio for water,... | |

...from air through a lens, I need not detain the reader by explaining. It is expressed in these terms : The sine of the angle of incidence is to the sine of the angle of refraction as the index of refraction of the lens is to 1. Thus if the lens be of water, the sine of the angle of... | |

...surface of the medium, so that it docs not issue from it at all. Suppose a ray of light entering air from water. The sine of the angle of incidence is to the sine of the angle of refraction in a constant ratio; as the angle of incidence is increased the ray issues at an angle which... | |

...quite intelligible to everyone, and the use of which therefore is unpleasant. However, it is, that the sine of the angle of incidence is to the sine of the angle of refraction as 4 to 3 (or nearly that). This is a sad way of putting it, but it means that the line GB, which is at... | |

...from the lens. 13. When a ray of light enters water it is bent from its path in such a manner that the sine of the angle of incidence is to the sine of the angle of refraction in the constant ratio of 4 : 3. ABC is the surface of the stream, and DGP is its bottom.... | |

...from air into the medium. On passing from the air into water, the ray of light is so refracted that the sine of the angle of incidence is to the sine of the angle of refraction, as 4:3; the refractive index is = (or 8 more exactly = 1'336). With glass the proportion is : 1620, Descartes).... | |

This amounts to the same with saying, that, in the case before us, the sine of the angle of incidence is to the sine of the angle of refraction in a given ratio.
