Apparatus for Investigating the Change of Frequency of Stationary Waves in a String
Product Code : JL-GLE-11268
The Apparatus for Investigating the Change of Frequency of Stationary Waves in a String, SKU JL-GLE-11268, is a JaincoLab standing wave apparatus. A wave generator, driven from the input signal generator, vibrates one end of a cord or elastic thread; the other end runs over a fixed pulley to a hook carrying masses of 50-100 g, which set the tension. Adjusting the frequency produces stationary waves with clear nodes and antinodes between the generator and the bridge.

Standing wave investigations
Students use it to explore:
- How the number of loops changes as the signal frequency is varied
- How tension, set by the hooked masses, changes the frequency needed for each harmonic
- Measuring the distance between nodes to find the wavelength
- Wave speed on the string from frequency and wavelength

Frequently asked questions
What drives the string?
A wave generator fed from the input signal generator.
How is the tension set?
With the hooked masses of 50-100 g hanging over the fixed pulley.
Can the string be elastic?
Yes; the listing gives a cord or an elastic thread.
What is the fixed pulley for?
It carries the string over the edge so the hooked masses hang freely and keep the tension steady.
