Sound Wave Experiments

In this video, we are going to look at the factors that influence the speed of sound and how to measure it.

We will look at sound waves in more detail in another video: Sound Waves

Sound travels at about 340m/s in air. At sea level. At 20 degrees celsius.

What does this tell us?

That temperature and air pressure affect the speed sound can travel through air. And this speed changes again for different mediums.

How is this possible? It’s all to do with particles. Let’s look at some evidence.

So sound travels at about 340 m/s in air.
In water, it travels at 1500 m/s, While in some solids sound can travel at up to 5000 m/s.
That’s incredibly fast compared to air!!

These differences are due to how particles are arranged in solids, liquids, and gases.
