Question
How can the chromatic abrration be corrected :
Options
A.By providing different suitable curvature to its two surface
B.By combining it with another lens of opposite nature
C.By reducing its aperture
D.By providing proper polishing of its twosurface
Solution
Chromatic abrration takes place when white light is used as source. We get a series of images overlapping each other and made by a lens. By using combination of lenses of opposite nature (convex & concave) wecan reduce this aberration.
