Question

Sound can travel through​

Answer 1

Answer:

Solids, liquids and gases.

Answer 2

Answer:

Any medium; It can't travel in a vacuum

Explanation:

Sound can be thought in a simple thought experiment:

Imagine dominoes, or chips, stacked vertically without touching each other but with a distance of less than a centimeter between adjacent dominoes.

Now, if you push the first domino, it will fall on the next one, which will fall on the next one, and so on. So, the small push on the first domino managed to travel a long distance before the dominoes stop falling.

In the same way, when you create a sound vibration, it travels through the medium, through the medium particles which act like the dominoes.

But, in the first case, if there were no dominoes, then how would the dominoes fall? In the same way, if there are no medium particles, then sound won't travel. So sound requires a medium to travel.
