Detailed explanation-1: -Sound wave is an example of mechanical wave. Mechanical waves require a medium to travel. Hence, sound waves cannot travel in vacuum.
Detailed explanation-2: -Sound waves cannot travel through a vacuum. They need a physical medium to travel through. This is because they propagate mechanically by moving material particles.
Detailed explanation-3: -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.
Detailed explanation-4: -Mechanical wave depends on particle interaction to transport their energy from one location to another. They cannot travel through vacuum, which are void of particles.
Detailed explanation-5: -Sound waves are classed as mechanical waves because they pass through a physical medium such as air, liquids like water, or metals like silver. A sound wave’s frequency is defined as the number of rarefactions and compressions per unit of time.
