A wave motion apparatus with 18 pulleys is a scientific tool used to demonstrate and study wave motion. It’s commonly used in physics education to help students understand wave phenomena, such as:
wavelength, amplitude, frequency, wave speed, standing waves, and interference patterns.
Here are some other uses of a wave motion apparatus: Demonstrating the movement of progressive transverse waves, Demonstrating longitudinal and transverse wave motion, and Performing experiments and tests.
A wave motion apparatus typically consists of 18 eccentric discs that support a series of metal rods. When the handle is revolved, the motion is transmitted from one rod to the next, appearing as a wave traveling to the top and back. The apparatus is made from tough, tensile materials and is robust in construction. The base of the apparatus is typically made of solid wood or metal.
