...convex mirror are made to diverge more than before reflection. SECTION III. REFRACTION OF UGHT. 417. When a ray of light passes out of one medium into another of a different density, it changes its direction at the point which separates the two media. This phenomenon... | |

...from a focus q, where Subtracting (i) from (ii) (ii). 52. It can be shewn that when a ray is refracted out of one medium into another, as the angle of incidence increases, so also does the Deviation. Art. 34. This principle, which admits of an easy Geometrical proof, will... | |

...2, 1, and Concave to the surface of the earth. 81. VARIATION OF EEFRACTION IN RESPECT TO ALTITUDE. When a ray of light passes out of one medium into another, the more obliquely it strikes the surface of the second medium the more it is refracted, and if it... | |
