Sound is the movement of compression waves (longitudinal waves) hitting our ears. These compression waves are alternating high and low pressure areas. The air molecules vibrate back and forth, but don't move. Speakers imitate sounds by pushing air and causing vibrations.
1 kwi 2018 · SPEED OF WAVES. 2 factors that determine the speed of a waves: Elasticity of the medium (how stiff the medium is) the greater the elasticity – the faster speed can travel. E.g. sound travels faster through steel than through rubber and faster in solids than liquids or gases.
Activity Overview. Students will engage in a series of demonstrations using a constructed amplifier that illustrates the several principles of sound. Students will learn about motion, forces, transfer of energy, and interactions of energy and matter. Steps*.
