Illustrate Standing WavesA wave generator with base, a clamp with pulley, a weight holder, and a string are used to demonstrate the concept of standing waves in this demonstration. The oscillator and string are used to generate waves at different frequencies, and the hanging mass and pulley can be used to measure the wavelength and amplitude. Connect the string with a hanging mass attached to the generator and turn on the apparatus - the number of nodes as well as distance between can be measured. Size: 25 x 18 x 7cm; weight: 1.6kg.
