A plano-convex lens with the radius of curvature R=-100mm is used to focus white light on a flat screen in air. The refractive index of glass in red light is n=1.5147 and in blue light is n=1.5228. Find the axial color and lateral color in the lens assuming the field angle of w = 5 deg. What should be the distance from the lens to the screen to minimize the chromatic aberration in the image?
