Sound: the Traveling of Sound

The video tutorial explains how vibrations produce sound, which travels through a medium as energy in the form of waves. Sound waves are longitudinal, with molecules moving parallel to the wave direction. A slinky is used to demonstrate this movement, highlighting areas of compression and rarefaction. The distance between consecutive compressions or rarefactions is defined as the wavelength.
