Transverse and Longitudinal Wave using Slinky
Product Code : SCL-ES-11436
Quick Answer: Transverse and Longitudinal Wave using Slinky is a flexible coiled spring that students stretch out to make both main wave types. Moving one end up and down sends crests and troughs along it, while pushing and pulling the end produces compressions and rarefactions.

Key Features
- Flexible coiled spring that acts as a one-dimensional medium for waves
- Shows transverse waves as crests and troughs moving along the stretched coil
- Shows longitudinal waves as compressions and rarefactions along the coil
- Lets teachers change amplitude and point out wavelength between successive crests or compressions

About This Product
The slinky makes the difference between the two wave types easy to see: in one the coils move at right angles to the direction the wave travels, in the other they move along it. Teachers use it to relate longitudinal waves to sound in air, to compare S-waves and P-waves in earthquakes, and to show that a wave carries energy without carrying the medium with it.
Frequently Asked Questions
How is a longitudinal wave made with the slinky?
Stretch the slinky and push and pull one end along its length. Bunched coils (compressions) and spread-out coils (rarefactions) then travel along the spring.
How is a transverse wave made?
Move one end of the stretched slinky quickly up and down, at right angles to its length, and crests and troughs run along the coil.
