Low-Friction Triple-Tandem Plastic Pulley, 25/38/50mm Diameter Physics_Alternative Energy and S-wave vs P-wave behavior

and S-wave vs P-wave behavior

this metal wave apparatus pairs the rotary handle with a degree scale so students can read phase against vertical displacement

and energy transfer in a compression wave

Die-cast body with plated brass parts anchors this cork-lined two-prong universal clamp

this cast double burette clamp secures two burettes side by side for back-titration and comparative analytical procedures

Low-Friction Triple-Tandem Plastic Pulley, 25/38/50mm Diameter Physics_Alternative Energy and S-wave vs P-wave behaviorTriple tandem plastic pulley with 25 38 50mm ball bearing wheels on an open sided 17. 6cm steel frame, eliminating cord threading during setup in compound pulley experiments.
