As defined by the scientific community, vacuum is defined as the empty space in which there are no matter particles present. Due to the fact that sound is a mechanical wave, a material medium is necessary for it to propagate. It is impossible for sound to travel in a vacuum because there are no particles present for vibrations to occur.
When it comes to space, sound does not travel at all. Almost no oxygen can be found in outer space due to the vacuum of space. Because sound is simply the vibration of air, there is no sound in space because there is no air to vibrate.
Why is there no sound in space?
There is no air in outer space (or anything else, for that matter). As a result, sound has nowhere to travel through, which explains why there is no sound in the vacuum of space. What is the path taken by electromagnetic waves as they go in a vacuum? An electric charge vibrates, and this causes electromagnetic waves to be produced in the process.
Why does a vacuum have no vibration?
There can be no vibration of something if there is no substance present (which is the basic definition of a vacuum). This is the polar opposite of the process of ″light waves,″ which are photons in the electromagnetic spectrum and appear to move very well in a vacuum, as described above.
Why can’t mechanical waves travel in a vacuum?
Mechanical waves, in contrast to electromagnetic waves, cannot propagate in a vacuum since they require the vibration of matter in order to do so. As a result, they can only be transferred through a media. There are three foods that are hazardous to dogs.
