  • A lens immersed in a liquied becomes in visible when

    A
    the focal length of the lens is zero
    B
    the focal length of the lens is infinite
    C
    the refractive index of the lens is less than the refractive index of the liquid
    D
    the refractive index of the lens is equa to the refractive index of the liquid

  • Focal length of a lens in air is f. Refractive index of the lens is mu . Focal length changes to f_(1) if lens is immersed in a liquid of refractive index (mu)/(2) and it becomes f_(2) if the lens is immersed in a liquid of refractive index 2 mu . Then

    A
    `f_(1) = (f)/(2)`
    B
    `f_(2) = -2f`
    C
    `f_(2) = -(3f)/(2)`
    D
    Data is insufficient
