    The dispersive power of the material of lens of focal length 20 cm is 0.08. The longitudinal chromatic aberration of the lens is:

    A)  0.08 cm               

    B)         0.08/20 cm

    C)  0.016 cm      

    D)         0.16 cm

    E)  1.6cm

    Correct Answer: E

    Solution :

    Longitudinal chromatic aberration = dispersive power \[\times \] focal length \[=0.08\times 20=1.6\text{ }cm\]
