Question

marcus plucks at an outstretched coil and observes the following wave motion. what is the motion of the particles in this kind of wave? wave motion → the particles will move up and down over large areas. the particles will move up and down over small areas. the particles will move side to side over small areas. the particles will move side to side over large areas.

Explanation:

The wave shown is a longitudinal wave (like in a slinky when plucked horizontally). In longitudinal waves, particles oscillate parallel to the wave's direction (side - to - side here) and within small areas (since they oscillate around their equilibrium positions, not large - scale movement). The first two options are for transverse waves (up - down motion), and the last option is incorrect as particles don't move over large areas. So the correct option is the one about particles moving side to side over small areas.

Answer:

The particles will move side to side over small areas.
