What must be present for sound to travel?

Answer 1

For sound to travel, three main components are required: a source of vibration, a medium through which the sound waves can travel (such as air, water, or a solid material), and a receiver to detect the sound waves (such as a human ear or a microphone). When an object vibrates, it creates sound waves that travel through the medium as a series of compressions and rarefactions, which are then detected by the receiver as sound.

Answer 2

Sound needs a media to propagate. Sound can not propagate in a vacuum. Sound waves, unlike light, are essentially compression waves and the sound in order to move from one place to other needs molecules to compress and decompress against, hence the wave is transmitted. In a vacuum, there are no molecules. Hence no sound.

Answer 3

One of the 3 states of matter, aka: gas, liquid, solid. Sound can't travel through nothing! A medium for the sound to travel through. Sound is caused by vibrations in something that cause vibrations in your eardrum. If there is nothing for sound to travel through, nothing to vibrate through to get to you, then there is no sound. Examples: Space is a vacuum, therefore no sounds can be heard. Water vibrates slowly with sound, therefore sounds can't be heard distinctly or well and they don't travel as far. Air vibrates well, sound can travel easily.

Answer 4

There must be particles present for sound waves to travel. Sound travels by vibration, when one particle hits another. This is why there is no sound in a vacuum as no particles are present.

Therefore, sound travels better within a space with a higher concentration of particles. For example, sound travels faster through a solid as opposed to a liquid or gas.

Answer 5

A medium, like air. In a vacuum sound waves cannot travel.

Answer 6

Particles bumping into one another. Example: falling dominoes/ newton balls
