Singing Rods
Striking or stroking the end of an aluminum rod while holding the center between fingertips excites a simple longitudinal standing wave. The speed of sound in aluminum is found by measuring the length and finding the frequency (using #15855 Frequency Finder). A second rod creates 'beats' when sounded with the first. Includes real rosin for fingertips and earplugs for the demonstration.

Super Spring And Stand
This extra long large spring (stands 20 cm high when compressed) allows students more time to observe wave behavior. The concern over tangling during use or storage is solved with the included stand. An accompanying Teacher's Guide includes the motion of waves through a medium, how waves interact with each other, how energy is transferred through a spring, and the Law of Superposition.

Ripple Tank Large with accessories
The ripple tank is an essential physics teaching tool both for demonstration and lab work. With this important aid reflection, refraction, diffraction and interference are easily investigated. The meaning of wavelength, velocity, frequency and phase become very clear in this lively way of matching concept with vocabulary using various wave generators, reflectors, apertures and plates. Our design uses heavy gauge molded parts with internal...
