Chromatic aberration can be significantly reduced by using an achromatic doublet, a converging and a diverging lens combination with the lenses in contact. You need to make a 12x achromatic eyepiece in which the converging lens has a focal length of 2.0 cm. Part A What focal length diverging lens should you use? Express your answer to two significant figures and include the appropriate units. fdiv = - 2.6 μA cm ?
