Question

Which method is used to minimize the chromatic aberration in the spherical lenses?

• A. By using concave lens
• B. By using convex lens
• C. By combining concave and convex mirrors
• D. By combining concave and convex lenses

Answer 1

The correct option is D By combining concave and convex lenses

To minimize the chromatic aberration, the combination of thick concave and convex lenses is used or even two thin convex lenses with proper separation are used.
