...philosophers have discovered a common law or rule of refraction applicable to all media. It is this : 790. The sine of the angle of incidence and the sine of the angle of refraction have always a fixed relation or ratio, whatever the obliquity of the incident ray may be, so long as... | |

...surface; contrarywise, away from the perpendicular. Q. What is the index of refraction? A. It is the ratio between the sine of the angle of incidence and the sine of the angle of refraction. Air is regarded as the standard medium, and the ratio between the sines of the angles made by a ray... | |
