Abstract
Most of us are familiar with the waves that bob on the surface of the ocean. Some of us can even tell stories of the "stomach" memory of such waves! But most people don't know that the ocean also has waves that bob deep below the surface. Besides being interesting in their own right, these so-called "internal waves" provide a convenient way to explain some key concepts in Physics. I'll outline such topics here, along with an experiment that can be done by students.
