Forum Thread: What Is Sound?

In this video i try to make an approachable explanation of what is sound.

Because is something so fundamental in our lives, deserves to be understood in physical terms but don't worry, this is a simplified version.

First is explained how sound is a vibration and a wave, then is approached a very important property of sound, Frequency.I also talk about the speed of sound and how it changes with the medium in wich it propagates.In the end i mention some cool applications of sound like breaking glasses, visualizing sound and levitating small objects.

Credits/resources can be found in my YouTube description.
