Slinky Coil – Interesting Tricks and demonstrations of Transverse and Longitudinal Waves
Slink coil is usually used to demonstrate the two types of waves – transverse and longitudinal waves. But remember that when you are asked to state an example of each wave, do not quote slinky coil.
View the videos below to know more about the two types of waves.
Using Slinky Coil to demonstrate Transverse and Longitudinal Waves
Though slinky coil is commonly used to demonstrate transverse and longitudinal waves, you must not quote it as an example for either of the waves.
- Transverse waves are waves in which the direction of the wave is perpendicular to the direction of the vibration of the particles. Examples are light wave, water wave or all the waves in the electromagnetic spectrum (which light is one of the waves.
- Longitudinal waves are waves in which the direction of the wave is parallel to the direction of the vibration of the particles. Example is sound wave.

Students are confused when they need to visualise what is the direction of the particles the next moment of the wave. There is a simpler way solve such question.

Waves Summary – Amended
Transverse Waves and Longitudinal Waves
Transverse waves are waves in which the direction of the wave is perpendicular to thedirection of the vibration.
e.g Light, water, and any waves in the electromagnetic spectrum
Longitudinal waves are waves in which the direction of the wave is parallel to the direction of the vibration.
e.g Sound
Wave equation: V = fλ
From the rope videos, with only vertical displacement, speed of wave is constant.
Hence frequency is inversely proportional to wavelength. [f increases, λ decreases, and vice versa]
