Apparatus Review: Cenco Wave Apparatus
Some apparatus from the 19th century illustrates the phenomena of physics so well that it crops up again in the 21st century. An example is the combined transverse and longitudinal wave machine in Fig. 1. This is in the current Cenco/Sargent-Welch catalog under the name of “Wave Apparatus” (Cat. No. WLS-1755-90) and sells for $49.95.
