Quick Answer: The Transverse and Longitudinal Wave using Slinky is a hands-on wave model in which a slinky spring shows both transverse waves and longitudinal compressions and rarefactions.
Last updated: October 2026
Key Features
Demonstrates both transverse and longitudinal wave motion.
Up-and-down or side-to-side movement produces a transverse wave.
Push-pull movement along the spring sends compressions and rarefactions through it.
Explains crest, trough, amplitude, wavelength, frequency and energy transfer.
Manual operation with no electricity needed.
About This Product
The slinky is held between two students, or between a student and a fixed support, and stretched gently in a straight line without overextending the coils. Moving one end up and down shows coils moving perpendicular to the direction of wave travel, while pushing and pulling along the length sends compressions and rarefactions through the spring. Students then compare the motion with textbook wave diagrams. Export supply of the Transverse and Longitudinal Wave using Slinky can be arranged to laboratories and schools in Sri Lanka, Indonesia, Kuwait, Trinidad and Tobago and Bhutan.
Frequently Asked Questions
Q1. How does the slinky show a longitudinal wave? Push and pull one end along the length of the spring so that compressions and rarefactions travel through the coils, the same ideas used in sound wave lessons.
