Yellow Waves

This summer, I went to Arizona where we did a lot of driving. There were tons of open fields filled with either grass or wild flowers. As the elevation increased, it got windier. When the wind blew the flowers in the open fields, it looked like there were waves. We've studied two kinds of waves so far, transverse and longitudinal. These paricular waves that I saw in the fields were longitudinal, meaning that the waves traveled across from left to right and so did the flowers. Transverse waves are the opposite in a sense that while the wave travels across from left to right, the object creating the wave moves up and down. An example of a transverse wave would be a flag.
