    Question

    Light travels from air into water with an index of refraction of 1.33 . The light ray will:

    A.

    go perpendicular to the normal

    B.

    bend away from the normal

    C.

    bend towards the normal

    D.

    go parallel to the normal

    Correct option is C

    The correct answer is:(C). bend towards the normal
    Here's why:
    • Refraction: When light travels from one medium to another with a different density, its speed changes, causing it to bend. This bending is called refraction.

    The light ray will bend towards the normal as it travels from air into water.

    • Denser Medium: Water is denser than air, meaning light travels slower in water.
    • Bending: When light enters a denser medium (like water from air), it bends towards the normal. The normal is an imaginary line perpendicular to the surface at the point where the light enters.
