Chromatic Aberration. - Demonstration. - Place a large double convex lens perpendicular to the sun's rays (Fig. 1). If a screen is placed at S, a picture of the sun will be formed having an outer fringe of red, but if the screen is placed in the position S' the fringe will be violet.
This effect, which is quite common in single lenses, is called chromatic aberration, and is due to the unequal refraction of the different colors.
