Consists of several sections, each section has a large A-frame base with a series of steel rods attached at their centers to a torsion wire. This machine produces slow moving, high amplitude transverse waves and can be used to demonstrate:

• Wave propagation
• Wave length versus velocity and frequency
• Standing waves
• Reflection at fixed and free boundaries
• Constructive and destructive interference

Each section has rods of different lengths.

• Section 1: 91 cm long, 46 cm rods
• Section 5: 91 cm long, 46 cm rods
• Section 2: 91 cm long, 23cm rods, resulting in a wave velocity that is 3 times as fast.
• Section 4: 59 cm long, with rods that vary from 23 to 46 cm. This section acts as an impedance matching unit.
• Sections 3 and 6: 91 cm long, 46 cm rods (older machines, will work okay if an extra long wave machine is desired.

Sections can be attached as (1 or 5) – 4 – 2 for one very long section, or as 1 – 5 and 2 – 4 for two long sections.

This set also includes clamps which act as rigid/reflecting boundaries, a dashpot for liquid damping, and couplers for connecting sections together.
