प्रश्न
Fill in the blank and explain.
Sound does not travel through ______.
उत्तर
Sound does not travel through Vaccum.
Explanation:
- Sound waves need to travel through a medium such as a solid, liquid, or gas.
- The sound waves move through each of these mediums by vibrating the molecules in the matter.
- Sound cannot travel through a vacuum.
- 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.
