t A be the point of incidence on a surface separating air fromwater. With A as a centre, describe a circle, BmCp. Let LA bean incident ray, and AK the refractedray. Draw mn and pq perpendicularto the normal. BC. Then will theselines be the sines of the angles of inci-dence and refraction, and we… … Refractive power of Bodies. 28iy. Different bodies possess different refractive powers. New-ton observed that, as a general rule, the refractive power wasgreatest for combustible bodies, or bodies containing combustibleelements, such as alcohol, ether, oils, &c, which contain both hydro-gen and…
