...It is the ratio of the velocity of the incident to that of the deviated light, which is equal to the **ratio of the sine of the angle of incidence to the sine of the angle of** refraction or of reflexion, according as m is positive or minus unity. The numerical value of m, has... | |

...ray, the refracted ray, and the normal, are all in the same plane. 2nd. For the same two media, the **ratio of the sine of the angle of incidence to the sine of the angle of refraction is** constant, whatever may be the angle of incidence. This law has received the name of " the Law of Descartes."... | |

...perpendicular to oc, then whatever the angle of incidence may be, the ratio — remains the same. BT The **ratio of the sine of the angle of incidence to the sine of the angle of refraction is** termed the refractive index for the given media. 37. Having given the direction of the incident ray... | |
