Q

What happens to the amplitude over time (use the word we talked about)? Why?

A

Over time, the amplitude, or the degree of displacement, decreases over time due to friction. This is called damping. This is shown by comparing the degree of displacement at points B and D versus points H and J.

Q

How do you know if the wave is at a point of compression?

A

Compression is when particles are spaced closely together and when pressure is high. This occurs as the particle moves closer to the point of rest.

25
How do you know if the wave is at a point of rarefaction?
Rarefaction is when particles are spaced further apart and pressure is low.
26
Explain the particles movement (where it is, what is happening to it, and why)
In the graph at Position A, the particle is at the point of rest, then, due to force, moves toward Position B. Position B is maximum positive displacement, where velocity is at 0 and a change in direction occurs to due elasticity. At Position C, the particle passes through the point of rest, where maximum velocity occurs and minimum displacement occurs. Due to inertia, the particle continues to move past Position C in a negative direction to Position D. At Position D, maximum negative displacement occurs and velocity is at 0. Again, due to elasticity, the particle moves in the opposite direction toward Position E at the point of rest. This concludes one complete wave and this continues to occur, until friction and damping causes displacement to decrease.
