उत्तर

Sound does not travel through vacuum.

Explanation:

  1. Sound waves need to travel through a medium such as a solid, liquid, or gas.
  2. The sound waves move through each of these mediums by vibrating the molecules in the matter.
  3. Sound cannot travel through a vacuum.
  4. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
