When sound waves strike polystyrene balls, they create vibrations in the surrounding air. These vibrations are transferred to the balls, causing them to move. The extent of this movement is influenced by the sound wave’s frequency. For instance, lower-frequency sounds, like bass, produce larger, slower motions, while higher-frequency sounds, such as sharp tones, result in quicker, smaller movements. This interaction illustrates how sound waves affect their environment, including objects like pol
