...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 — (or more 3 exactly = 1-336). With glass the proportion is -3 : 2-1-535—... | |

...the surface, coincident with the normal, it is not refracted. When water is the refracting medium, the sine of the angle of incidence is to the sine of the angle of refraction as 1^ is to 1, or 1.336 to 1, (this number is called its index of refraction, or refractive power), while... | |

...has been properly made, it will be 15 mm. in length. Since the index of refraction of water is 1.332, the sine of the angle of incidence is to the sine of the angle of refraction as 1.332 is to 1.0, or as 4 is to 3. The sine of the angle of refraction will therefore be 11.25 mm. Set... | |

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.
