  • question_answer
    A lens behaves as a converging lens in air and a diverging lens in water. The refractive index of the material is [CPMT 1991; NCERT 1979; BHU 2005]

    A)            Equal to unity                      

    B)            Equal to 1.33

    C)                  Between unity and 1.33         

    D)            Greater than 1.33

    Correct Answer: C

    Solution :

               \[{{\mu }_{air}}<{{\mu }_{lens}}<{{\mu }_{water}}\] i.e., \[1<{{\mu }_{lens}}<1.33\]
