Apparatus for Demonstrating the Propagation of Waves
Product Code : JL-GLE-11263
The Apparatus for Demonstrating the Propagation of Waves, SKU JL-GLE-11263, is a JaincoLab wave motion demonstrator for showing transverse and longitudinal waves side by side. Turning the handle rotates a set of eccentric discs, each carrying a metal rod, and the rods rise and fall one after another so a transverse wave appears to travel along the row; bent rods produce a longitudinal wave in the same way. The listing adds aluminium pulleys, a 0-6 V vibrator 15.6 mm in diameter and a 450 x 200 x 300 mm working range.
