    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    [UPSEE 2004]

    A)            0.1 m                                       

    B)            0.2 m

    C)            0.3 m                                       

    D)            0.4 m

    Correct Answer: B

    Solution :

                       For minimum spherical and chromatic aberration distance between lenses.            \[d={{f}_{1}}-{{f}_{2}}\]\[=0.3-0.1\]\[=0.2\,m\].
