...colourless glass is shown as a function of wavelength expressed in nanometres ( 1 nm = 10~9 m). that the sine of the angle of incidence divided by the sine of the angle of refraction is equal to the ratio of the refractive index of the second medium to the refractive index of the incidence... | |

...corresponding angle in the air (angle of incidence). Mathematically, the refractive index is the ratio of the sine of the angle of incidence divided by the sine of the angle of refraction. The measurement of the refractive index (-ยป refractometer) serves to test transparent liquids, like... | |

...divide o'm' by n'p', we will have in both cases the same quotient, or, as it is generally expressed : the sine of the angle of incidence divided by the sine of the angle of refraction is a constant, whatever the angle of incidence may be. This constant quotient is called the index of... | |

It may also be defined as the sine of the angle of incidence divided by the sine of the angle of refraction, as light passes from air into the substance.
