I'm trying to figure out what happens to a tension-ed anchor line when encountered by a surface wave (transverse and longitudinal ) Assuming a 2 dimensional view, or that the cable is sufficiently wide that the wave cannot go 'around it' what happens to the path and speed of the surface wave . Is a portion of the wave encountering the boundary reflected by Snells way from the boundary? (upward) Is the reflection coefficent higher the higher the tension in the cable ? As speed is directly proportional to tension Does the portion transmitted to the anchor cable travel along its length at faster speed . Does the transmitted portion also transmit thru to the water below returning to the same speed? Is the outcome related to only one component transverse or longitudinal or is it the same ?
