Iris: Seismic Wave Behavior: A Single Boundary Refracts & Reflects

Curated by ACT

This introduction to seismic wave behavior describes Snell's Law and how it applies to layers in the earth. It addresses reflected, refracted, critically refracted, and head waves. Seismic waves travel at different speeds through different materials. In this 2-layer model two wave fronts leave an impact at the same time but the lower layer is faster. [2:18]
