Thinking About Waves
We go out to Lake Jordan some Sundays, for a kayaking adventure. This past weekend, we took a tandem out for a couple hours, myself, Susan, and Benji in his life vest (he actually has two!). Across the channel, off to the west, around the big bend of the shore. We pulled into a little beach and we all jumped out of the kayak for a swim in the very warm water. The lake bottom, all clay and silt, was squishy with dead sticks popping out. In the middle of the lake, boats cut big waves into the water that slowly radiated out to us. Nearer, the surface was not exactly smooth, but crinckled with lots of high frequency little waves. As the two waves combined, I was transfixed watching the resultant sum. I thought about WiFi and wondered if CCK modulation - which I've been reading about lately and is quite complicated - does something like waves on Jordan Lake. Gawd, I love waves. The pink wave sums a deep, slow wave (blue) plus a small, fast wave (red). Courtesy of http://www
