Sound waves are really interesting! They move through different materials like solids, liquids, and gases, and each of these materials affects how sound travels. Let’s take a closer look at how sound moves in each of these mediums.
In solids, sound travels the fastest.
This happens because the molecules in solids are packed closely together.
When you knock on a metal door, the sound zooms through the metal. That’s how someone on the other side hears it almost instantly.
In steel, sound can travel at about 5,960 meters per second!
Next up are liquids, like water.
In liquids, the molecules are not as close together as in solids but are still closer than in gases.
This means sound travels at a medium speed in liquids.
For example, in water, sound travels at around 1,482 meters per second.
Have you ever tried to talk underwater? That’s because sound moves pretty well in liquids!
Finally, we have gases.
Sound is the slowest in gases because the molecules are far apart.
For instance, in air, sound travels at about 343 meters per second.
This is why we see a flash of lightning before we hear the thunder.
The sound has to travel through the air, which takes a little more time.
To wrap it up, sound waves travel differently depending on the material:
Knowing how sound works helps us understand the way it interacts with different materials!
