Showing Wave Patterns with A String
Description: One end of a 12-foot long string is attached to a door or faucet and the other attached to an electric drill through a special adapter. Once the drill is turned on, a wave is produced. The number of nodes in the wave can be changed by varying the speed of rotation of the string.
