    A this glass prism (\[\mu \] = 1.5) in the position of minimum deviation deviates the mono chromatic light ray by \[10{}^\circ \], the refracting angle of prism is:

    A)  \[20{}^\circ \]                  

    B)                         \[10{}^\circ \]                                  

    C)         \[30{}^\circ \]                                  

    D)         \[45{}^\circ \]

    Correct Answer: A

    Solution :

    Given: \[{{\delta }_{m}}=10{}^\circ ,\,\mu =1.5\] For a thin prism of minimum deviation \[{{\delta }_{m}}=(\mu -1)A\] \[10{}^\circ =(1.5-1)A\] or \[A=\frac{10}{0.5}=20{}^\circ \]
