Relfection on Mini Wave Experiment.

How do waves interact in a tub of water with?
No barriers
One barrier
Two barriers

We filled a low, shallow tub with about two cups of water, we then used our fingers to make the wave and pieces of clay were used as barriers. During this experiment we noticed many different things and in the picture below you can see some of our observations:
If you cane see, the black dot stands for the source of the wave, the wi-fi or ripple type lines are supposed to be the wave and how to interacts with whatever other wave is inside te water and last but not least there is the blocks which are supposed to be the barrier. As you can see in these sketches, especially in sketch number 2,6 and 11 is that these waves, when interacting without a barrier simply intersect and the try to continue on, almost on top of each other. When two waves interact with two waves you usually see that the wave gets up to about the barrier, the wave that can make it through the middle goes through the middle and the remaining waves bounces back. Now when there is one barrier and one wave you can see that usually part of the wave that is not hitting the barrier will continue on in a smaller wave but the part that is hitting the barrier does travel back. So when you conclude you see that waves travel back when they interact with something and that is when they continue on in smaller waves. But when waves interact they simply smother each other.
