  • question_answer
    Three prisms 1, 2 and 3 have the prism angle A = 60o, but their refractive indices are respectively 1.4, 1.5 and 1.6.  If d1, d2, d3 be their respective angles of deviation then [MP PMT 2001]

    A)            d3 > d2 > d1                             

    B)            d1 > d2 > d3

    C)            d1 = d2 = d3                             

    D)            d2 > d1 > d3

    Correct Answer: A

    Solution :

               \[\delta \propto (\mu -1)\]
