In this lab my partner and me did nine tests 3 for each group. Three for no barriers three for one barrier and three for two barriers. No Barriers
In the first experiment the waves traveled quickly and met in the middle of the pan making a more dense part there. In the second experiment the waves slid through each other and continued on, the other wave just slowed it down. The waves in the third experiment intercepted each others way meeting in the middle but both of them continued there journey to the other side of the pan.
One Barrier
In the first experiment the waves hit the barrier and slightly bounced off in a slighter form. In the second experiment the waves break up and bounce of the wall they return back in a slighter form. In the third experiment the waves split up but later rejoin.
Two Barriers
In the first experiment part of a wave passe the pass and the other bounce off the play dough and come back. In the second experiment. In the second experiment most of the waves bounce off the play dough and a few pass through the opening and bounce off the other side. In the third experiment most of the waves hit the walls of the play door enclosure but a few pass through the openings and reach the other side.
Conclusion
After doing this lab I can see how waves interact with barriers and without and how even with small passes some of the waves manage to go through them. Waves always some how find a way to travel through another object even if it's another wave. They use diffraction to pass through a hole in a barrier. When ever waves reach each other which happens quite a lot they just pass through each other with a little decreased speed.
Good job Marko. Good organization and well-written conclusion. Does speed always decrease when they pass through each other?
