FMM MOVIES

A series of movies are included below to demonstrate several aspects of wave propagation that are not apparent from inanimate figures. Movies are provided both as animated gifs and Quicktime movies.

The first movie below shows a first-arriving wavefront propagating through a continuous medium.

The movie below shows a multiple occurring in a highly complex velocity medium consisting of four layers. Note that one layer pinches out at both ends of the model. The wavefront reflects three times from the top of the bottom interface and once from the bottom of the middle and top interfaces.
