When I looked at the wave simulator on this website
http://phet.colorado.edu/en/simulation/wave-interference this simulator helped me understand how different types of waves "look like" when they acqure, and what they can do to the surface they are hitting. This simulator really helped me during my test because I realized how sound waves, light waves and water waves differ.
Water Wave
Light Wave
Sound Wave
This is interesting. I like how you included the different wave images. Did you try all types of water waves with different frequencies and barriers?
