Question

This slinky wave represents a _____.

  1. Transverse wave
  2. Longitudinal wave
  3. Sound wave
  4. Water wave

hintHint:

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.
