The wave driver was made using a battery-operated toy car, and the apparatus can be<br \/>\nused to produce string waves at a fixed frequency. The working principle of the apparatus is as<br \/>\nfollows: shortly after the car is turned on, the wheel starts to turn at a constant angular speed. A<br \/>\nrod that is fixed on the wheel turns at the same constant angular speed, too. A tight string that<br \/>\nthe wave will be created on is placed at a distance where the rod can touch the string. During each<br \/>\nrotation of the wheel, the rod vibrates the string up and down. The vibration frequency of this rod<br \/>\nequals the wheel\u2019s rotation frequency, and this frequency value can be measured easily with a small<br \/>\nmagnet and a bicycle speedometer. In this way, the frequency of the waves formed in the rope can<br \/>\nalso be measured.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This study was done to develop a simple and inexpensive wave driver that can be used in experiments<br \/>\non string waves.
