Question
This slinky wave represents a _____.
- Transverse wave
- Longitudinal wave
- Sound wave
- Water wave
Hint:
A longitudinal wave has an alternating pattern of compressions and rarefactions.
The correct answer is: Longitudinal wave
- A longitudinal wave is a wave in which the particles of the medium are displaced in a direction parallel to the direction of energy transport.
- The slinky is stretched out horizontally and the end coil is vibrated back-and-forth in a horizontal direction.
- There are regions where they become pressed together(compression) and other regions where they are spread apart(rarefaction), representing a longitudinal wave.
- So, the correct option is b.
