f a ray from water to glass.—In the preceding pages thepassage of a ray from air to a medium such as water or glass has beendealt with. When the ray passesfrom one transparent medium toanother, the index of refractionmay be found as follows. Letthe index of refraction for a raypassing from air to,… … Fig. 527.- -Index of refraction for any twomedia.
