A:
Sound is a pretty interesting thing. When we hear a sound, were
actually hearing vibrations. A good example of this would be to drag a
stick across some concrete. When you move the stick across the
concrete, you can hear the scrape because of the stick rubbing on the
concrete. But if you move the stick faster, the sound has a higher
pitch. So if you move the stick the same distance at different speeds,
you get different sounds. The reason this happens is because the pitch
of sound depends on the frequency of the vibration. Frequency is
basically how close together the vibrations are. So the faster you make
the vibrations, the higher the pitch will be.
