Burko for all original materials (sources for nonoriginal materials available upon request) 1 Waves Physics includes only local interactions. The modern viewpoint excludes action at-a- distance, unlike Newton’s viewpoint, say. Waves are one of the mechanisms, a very important mechanism, by which a disturbance travels from one place to another. The other common mechanisms are conduction (e.g., electric currents) and convection (e.g., the bulk motion of boiling water in a pot), but we will not discuss these other mechanism here, only waves, also known as radiation. Ex. As an example for the creation of a disturbance at one place, having a remote effect, consider a dog. You step on its tail, and then, on the other side of the dog, it barks. In this example the propagation of the disturbance is not that of a wave....
