Optics of thick glass mirror
October 4th, 2022
Images in a very thick glass mirror may by slightly colored by dispersion. Draw two vertical lines, separated by about 2 cm, to represent the front (glass) surface and the rear (silver) surface of the mirror. About 2 cm in from of the mirror, draw the object-a white point source. (a) Carefully draw red and blue rays to represent the red and blue light. Show that there are separate red and blue images, and indicate their locations (Hint: to locate each image you’ll need two rays. Choose as one the ray perpendicular to the mirror.) (b) Where would the image be if the glass was removed, but the silver and everything else remained in the same positions? Would the image be colored in this case?
