Detailed Solution

The above statement is True.
Sound is formed by the vibration of particles in the medium through which the waves travel, such as air or water. Sound is also defined as a longitudinal wave composed of compression and relaxation. A vacuum is an enclosed space with no molecules or matter. As a result, sound cannot travel through a vacuum because there are no molecules or atoms to induce vibrations.
