1. Explore the sound simulation as you change the amplitude and frequency. Look for patterns and relationships.

2.Do the particles move in the same direction as the wave or perpendicular to the motion of the wave?

What do we call this kind of a wave? (transverse or longitudinal?)

3.Freeze and observe: are the particles closer together or farther apart in the white area of the wave-viewing area?

4.What is the name for this portion of a wave?

5.Are the particles closer together or farther apart in the dark area of the wave-viewing area?

6.What is the name for this portion of a wave?

7.Follow one red dot as the waves cross it. After a number of waves have crossed it what happens to its net displacement?

8.Do the particles ever move permanently across the field of view? If the particles are not moving, what is moving?

9.The graph is a graph of kinetic energy. How would you describe the difference between the energy at a peak and the energy at a trough?
