Impedance Matching - Shive Model
# 3B25.10


Description: Thin rods are mounted on a fine wire that twists easily. Displace the rod at one end to create a torsional wave or pulse. Sets of rods of different lengths are connected to show reflection and refraction with matched or unmatched impedances.
