How about the vertical motion? Is it the water (i.e., medium) that moves up and down or the wave? 2. To explore this, turn off the Timer and select Slow Motion. 3. Select the main image II to start continuous wave motion and move the vertical ruler so it is adjacent to the 2nd green bead. Do you notice that the green bead (representing a portion of the medium) just moves up and down while the wave crest moves to the right? You can single-step the wave motion as you did in Activity 2 if it helps to see this. 4. What do you conclude moves vertically and what moves horizontally in the water ripple
