object and mounting medium. With suchimages the diaphragm should not be too large (see \ 79). If the color and refractive index of the object were exactly like the mountingmedium it could not be seen. In most cases both refractive index and color differsomewhat, there is then a combination of color… … Figs. 53-55.—Diagrams illustrating refraction in different media and at planeand curved surfaces. In each case the. denser medium is represented by line shad-ing and the perpendicular or normal to the refracting surface is represented by thedotted line N-N, the refracted ray by the bent line A C. %…
