Question

In which of the following media can a mechanical wave travel?

  1. In a medium but not in a vacuum
  2. Neither in a medium nor a vacuum
  3. In a vacuum as well as in a medium
  4. In vacuum but not in a medium

hintHint:

In a medium but not in a vacuum

The correct answer is: In a medium but not in a vacuum

    Which of the following statements is/are correct about the waves?
    I. Waves are patterns of disturbance that move without the actual physical transfer of flow of matter.
    II. Waves cannot transport energy.
    III. The pattern of disturbance in the form of waves carries information that propagates from one point to another.
    IV. All our communications essentially depend on the transmission of signals through waves.
