Kit to study stationary waves
Product Code : SCL-ES-12772
Quick Answer: The Kit to Study Stationary Waves demonstrates standing waves on a stretched string or wire, showing nodes, antinodes and the link between frequency, wavelength and wave speed. One end of the string is driven by a vibration source while the other passes over a pulley with weights for tension.

Key Features
- Shows stationary (standing) waves on a stretched string or wire
- Nodes and antinodes can be seen and located along the string
- Changing the length, tension or frequency alters the wave pattern
- Distance between two consecutive nodes gives half the wavelength
- Supports wavelength, frequency and wave-speed calculations

About This Product
Stationary waves form when two waves of equal frequency and amplitude travel in opposite directions and interfere. With this kit a class adjusts the string until clear loops appear, measures the node spacing and uses it to calculate wavelength or wave speed, tying interference and resonance theory to a visible result. Enquiries from Bosnia and Herzegovina, Zambia, Iran, Trinidad and Tobago and Angola for the Kit to study stationary waves receive an export quotation.
Frequently Asked Questions
How is the wavelength found with the Kit to Study Stationary Waves?
Measure the distance between two consecutive nodes on the vibrating string. That distance is half the wavelength.
What changes the stationary wave pattern?
Changing the string length, the tension set by the weights or the vibration frequency changes the pattern until clear stationary wave loops form.
