Question

how sound travells and what is vibrations

Answer 1

Explanation:

Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. The further away from the original source of a sound you are, the waves lessen until they don't have the strength to vibrate any other particles. It's like when you throw a stone into a pond and it makes ripples that make more ripples until it slowly dies out.

Sound can move through the air, water, or solids, as long as there are particles to bounce off of. However, if there are not particles to bounce off of, it can't move. There is no sound in the vacuum of space, because there is nothing to vibrate the sound.
