Reading Magnifier, 75mm, 20cm Focal Length Safety Supplies_Eye Protection The wavelength can be changed

The wavelength can be changed with the help of variation in frequency & stress generated using different weights on the one end of rope/thread

The Emission Control training simulator is a comprehensive instructional module that plugs directly into the Advanced Autotronics Simulator workstation designed to train students on modern automotive emission control systems

The waves generated such are demonstrated using linear rope/thread

7 kΩ nominal resistance with 4mm-socket leads
