Sound is a form of energy, just like electricity and light. Sound is made when air molecules vibrate and move in a pattern called waves, or sound waves. Think of when you clap your hands, or when you slam the car door shut.That action produces soundwaves, which travel to your ears and then to your brain, which says, âI recognize that sound.â.hen we draw a sound wave, the wave peaks and valleys are close together or far apart. Sound waves vibrate at different rates or âfrequenciesâ as they move through the air. Frequency is measured in cycles per second, or Hertz, after the German physicist who experimented with sound in the 19th century.
