No.1 Barrier:
As my partner and I worked on our experiment, we started out as no barrier. Which side we taped on (diagonal, head to head) we found some different wave movements. Some wave movements interfered and collapsed to create larger wave, some went on different directions. But majorities of our no.1 barrier experiment, we discovered that when wave interferes, it natural goes its way. (ex. so, a boy walks from the left side of the street to the right side and on the other hand, the girl walks from right to left. Girl and the boy have to talk however they go as if they were strangers.) Another great thing about no barrier was, the wave moved back and forth.
No. 2 Barrier (With one block)
This experiment was bit unlike the first one. The clay had stopped the wave's movement from going its way, actually it led to another way. When the wave had to go across, the barrier made this to go the other way, the wave didn't go through the clay, and instead it just went side. The clay had a role like the mirror (reflecting), whenever the wave had hit the clay, it came back.
No.3 Barrier (With two block)
This was really arduous to track the movement of waves since it spread out to many places (we were dumbfounded at first). It just didn't made wave go back and forth, it stopped the wave from heading to its location (traffic jam). The wave had spread sideways, up and down, diagonally which formed something exquisite for us to observe. We found that when placing together directly in-front of the tapping location, and when tapping more; waves will go back and forth trying to create speed as fast as it can (speed and frequency).
This concludes that when trying to stop wave’s movement, wave will not go through but spread sideways, or when placing barriers just in-front of wave’s start and if tapping, water will move fast due to reflect of the barrier. (I guess that made sense)
The Diagram or Picture (Data):
Well done Kyle! You organized your observations and data very well and were able to discuss your conclusions in the end. Good job!
