    When a pencil is partly immersed in water in a slanting position, the immersed portion appears :

    A)  Curved downwards

    B)  Bent towards the water surface

    C)  Bent in a zigzag mannar

    D)  Bent towards the bottom

    Correct Answer: B

    Solution :

    [b] This is due to refraction: In this case the pencil appears bent because it is entering from a rarer medium to a denser medium i.e. from air to water. When a ray enters into denser medium, it bends towards the imaginary normal line (perpendicular to the surface of contact) therefore it should be bent towards the bottom.
