A student sends a beam of white light from a filament lamp at a glass prism in a dark room. Fig. 4.1 shows the white beam striking the left-hand face of the glass prism. A screen is positioned to the right of the glass prism. Red light is seen at point R on the screen and violet light is seen at point V.
