...and the normal to the refracting surface at the point of incidence are in one plane, (ii) The ratio of the sines of the angles of incidence and refraction is a constant, depending only on the nature of the media in which the light is propagated. It is important to express... | |

...incidence and reflection are equal. The law of refraction, known as Snell's law, states that the ratio of the sines of the angles of incidence and refraction is a constant which depends on the color of the light and_the nature of the two media; that is, •^- V^ sin i _... | |

...worked out for determining focal lengths and apertures. The true law of refraction, that the ratio of the sines of the angles of incidence and refraction is a constant depending on the media concerned, was discovered in 1601 by Harriot and rediscovered a few years before... | |

...ray bent at the surface of contact between the two media. It has been found that the ratio between the sines of the angles of incidence and refraction is a constant, and is equal to the ratio of the velocities of light in the two media. The equation may be written... | |

... the angle of incidence. This proportion (TU : SP) is, for example, for air and water as 4 to 3, whence it follows that at whatever angle the ray RI in the air may strike the surface of the water, the refracted ray IS will be so deflected that TU shall...
