    Sound cannot pass through –

    A Water Correct Answer Incorrect Answer
    B Steel Correct Answer Incorrect Answer
    C Air Correct Answer Incorrect Answer
    D Vacuum Correct Answer Incorrect Answer

    Solution

    Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing. Sound also travels through plasma. Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation). Sound cannot travel through a vacuum because it does not provide the medium to propagate.
