JEE Main & Advanced Physics Ray Optics Question Bank Refraction of Light at Plane Surfaces

  • question_answer
    Velocity of light in a medium is \[1.5\times {{10}^{8}}m/s.\] Its refractive index will be                                    [Pb. PET 2000]

    A)            8    

    B)            6

    C)            4    

    D)            2

    Correct Answer: D

    Solution :

               \[\mu =\frac{c}{v}\]\[=\frac{3\times {{10}^{8}}}{1.5\times {{10}^{8}}}\]= 2.
