: 5 A Converging Achromatic Lens Of 60 Cm Focal Length Is To Be Constructed Out Of A Thin Crown Glass Lens And Flint Glas 1 (36.67 KiB) Viewed 37 times

5. 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]
