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

  • question_answer
    If the speed of light in vacuum is \[C\] \[m/\sec ,\] then the velocity of light in a medium of refractive index 1.5 [NCERT 1977; MP PMT 1984; CPMT 2002]

    A)            Is 1.5 \[\times \] C             

    B)            Is C

    C)            Is \[\frac{C}{1.5}\]             

    D)            Can have any velocity

    Correct Answer: C

    Solution :

               \[\mu =\frac{C}{{{C}_{m}}}\Rightarrow {{C}_{m}}=\frac{C}{1.5}\]
