subducting plate has been detected in a majority of subduction zones LVZ may be a hydrated layer of oceanic crust caused by dehydration reactions as the plate subducts LVZ has interesting consequences for imaging the . Chapter :: 6. Snell’s Revenge!. Snell’s Law & Critical Refraction. Because seismic sources radiate waves in all directions. Some ray must hit interface at exactly the critical angle, . i. c. This critically oriented ray will then travel along the interface between the two layers. . Drag force. The surrounding fluid exerts pressure forces and viscous forces on an object. .. The components of the resultant force acting on the object immersed in the fluid are the drag force and the lift force. .
