    A thin prism \[{{p}_{1}}\] of angle \[4{}^\circ \] and refractive index \[1.54{}^\circ \] is combined with another thin prism \[{{p}_{2}}\] of refractive index 1.72 to produce dispersion without deviation. The angle of \[{{p}_{2}}\] is

    A) \[4{}^\circ \]           

    B) \[5.33{}^\circ \]                 

    C) \[2.6{}^\circ \]

    D) \[3{}^\circ \]

    Correct Answer: D

    Solution :

    Angle of deviation \[I\]Dispersion produced by both the prism will be equal \[I\] \[I\] Hence, the angle of prism \[I\] is \[I\]
