    For a medical the refractive indices for red. violet and yellow colour light are respectively \[1.52,1.64\]and\[1.60\]. The dispersive power of the material is:

    A)  2                                

    B)  \[0.45\]

    C)  \[0.2\]                         

    D)  \[0.045\]

    Correct Answer: C

    Solution :

    As, the dispersive power \[w=\frac{{{\mu }_{\upsilon }}-{{\mu }_{r}}}{{{\mu }_{y}}-1}\] \[w=\frac{1.64-1.52}{1.6-1}=\frac{0.12}{0.6}=0.2\]
