Sound Waves Cannot Travel Through

Travel of Sound Waves

Sound waves cannot travel through a vacuum. A solid, liquid, or gas-based medium is required for the propagation of sound waves. By causing the molecules in the material to vibrate, sound waves travel across each of these mediums. Solids contain closely packed molecules. Unlike solids, liquids are not as densely packed. Gases are also very slackly packed.

Sound can move through a solid much more quickly than gas due to the distance between molecules. In comparison to air, sound travels through water approximately four times quicker and farther. Particles in a medium, such as air, water, or metal, vibrate as sound waves pass through that medium.

Summary:

Sound Waves Cannot Travel Through

In a vacuum, there are no particles to vibrate, so sound waves cannot travel through it. A solid, liquid, or gas-based medium is required for the propagation of sound waves. Since there are no atoms or molecules in a vacuum to vibrate, they cannot move through it. Sound cannot, therefore, travel through a vacuum. However, sound can travel quickly through a solid or even a gas. The speed depends on the distance between the molecules of the medium it is passing through.
