## Homework Statement

I'm given a graph with displacement in metres on the y-axis and time on the x-axis. The graph represents the displace of a particle of a spring that has a mechanical wave passing through it

The graph is just a simple sine wave.

It then asks to describe the displacement of the particle compared to the velocity of the wave and then state and explain whether the wave is longitudinal or transverse.

## Homework Equations

## The Attempt at a Solution

Since the particles displacement is changing from positive to negative periodically I'm assuming the particle is oscillating in the direction of the waves velocity so therefore the wave would be longitudinal since the particle is vibrating parallel to the direction of motion of the wave?
