...passes obliquely from one medium to another it changes its direction, and is then said to be refracted. When it passes from a rarer to a denser medium,. it is refracted totaurds the perpendicular ; when from a denser to a rarer, it is refracted from the perpendicular.... | |

...too great by this depression. The correction for dip is therefore subtractive. When a ray of light passes from a rarer to a denser medium, it is bent towards the perpendicular, at the point at which it entered. This bending is called refraction. Now the strata of the atmosphere... | |

...but when it enters a medium of different density it is refracted, or bent, out of its former course. When it passes from a rarer to a denser medium it is refracted toward the direction of the ray of light, as can be seen by putting the end of a knife in... | |

...coronas or colored rings around the sun or moon in thin clouds. 63. Refraction. When a beam of light passes from a rarer to a denser medium, it is bent towards the vertical to the surface separating the two media; and the finer waved rays are bent more than those... | |

...light would pass from the air to the glass in the reverse direction. Thus we conclude that when light passes from a rarer to a denser medium, it is bent towards the normal to the surface at the point of incidence, and that, whatever the angle of incidence may be,... | |

...the air, it is bent away from the normal. The law of refraction is stated thus : When a ray of light passes from a rarer to a denser medium, it is bent towards the normal; when it passes from a denser to a rarer medium, it is bent away from the normal. 250. Lenses.... | |
