3B Scientific U8431805 Hand Held Wave Machine - 3m Length Physics Demonstration Tool for Classroom & Science Education Experiments

Demonstration equipment for displaying propagation, reflection, diffraction and superimposition of transverse waves. A chain of wooden double-ended pendulums joined together by a bifilar thread. Two handles allow the chain to be held by hand and excited. Pendulum weights are supplied for altering the moment of inertia. Number of double pendulums: 79. Length: 3 meters. Weight: approximate 0.8 kilograms.
