e. A converging achromatic lens of 60 cm focal length is to be
constructed out
of a thin crown glass lens and flint glass lens, the surfaces in
contact having
a common radius of curvature of 40 cm. If the refractive indices
and
dispersive powers are 1.5 and 0.018 for crown glass, and 1.6 and
0.036 for
flint glass. What will be the radius of curvature of the other
surface of each
lens? [2+2+2]
