Question

A combination of two thin convex lenses of focal length 0.3 m and 0.1 m will have minimum spherical and chromatic aberrations if the distance between them is (A) 0.1 m (B) 0.2 m (C) 0.3 m (D) 0.4 m

For minimum spherical and chromatic aberration d=F1-F2=0.3-0.1=0.2 m

Q. A combination of two thin convex lenses of focal length $0.3 m$ and $0.1 m$ will have minimum spherical and chromatic aberrations if the distance between them is

0.1 m

0.2 m

0.3 m

0.4 m

For minimum spherical and chromatic aberration $d = F_{1} - F_{2} = 0.3 - 0.1 = 0.2 m$
