  • question_answer
    Deviation of 5° is observed from a prism whose angle is small and whose refractive index is 1.5. The angle of prism is                         [MP PET 1990; Similar to Pb. PMT 2003]

    A)            7.5°                                          

    B)            10°

    C)            5°   

    D)            3.3°

    Correct Answer: B

    Solution :

               \[5=(\mu -1)A=(1.5-1)A\Rightarrow A={{10}^{o}}\]
