Waves

This is a picture from a while back, at that new Finding Nemo ride at Disneyland. With Submarines. Though I did not realize it at the time, there is a lot of physics action going on here. In this picture, the submarines moving around in the water are causing a disturbance and generating waves. The submarine ride is most likely generating bow waves. As the submarine moves forward, the waves will pile up in front. This happens becauase the submarine is moving faster than the waves that it is producing. The continuous overlapping of the wave crests makes the front end of the waves form a v shape, characteristic of bow waves.
