We have studied two types of mechanical waves. Which wave’s motion can be illustrated by a slinky or spring?

Question

A:
a mechanical wave
B:
an electromagnetic wave
C:
a longitudinal wave
D:
a transverse wave

Answer 1

The correct answer is C: a longitudinal wave.

In a slinky or spring, when you push and pull the coils in the direction of the wave travel, you create compressions and rarefactions, which are characteristic of longitudinal waves.
