    Question

    Which statement is correct regarding the propagation of

    sound and light in different mediums? I. Sound travels faster in water than in air. II. Light travels faster in water than in air.
    A Only II Correct Answer Incorrect Answer
    B Both I and II Correct Answer Incorrect Answer
    C Neither I nor II Correct Answer Incorrect Answer
    D Only I Correct Answer Incorrect Answer

    Solution

    Sound waves travel faster in water than in air due to the closer proximity of water molecules, allowing vibrations to be transmitted more quickly. However, light slows down when it passes from air into water because water has a higher optical density than air, reducing the speed of light. This phenomenon is crucial in various optical applications, including lenses and prisms.
