Re: Waves, WB #289
Wow, The above is a lot to digest. I apologize for being absent for a while: It seemed that the thread had died and coincidentally the weather was lovely so I went sailing instead of computing.. The source cited by Robm is especially interesting to me because it takes it as a "given" that water density changes wave behavior. Pieces of college physics are surfacing concerning the impedance of a medium which transmits waves. In classic wave theory when a wave hits an impedance change (perhaps a thermocline in this case) some wave energy is transmitted but refracted at an angle, and some is reflected. I wonder if there is some explanation hiding there for the observed differenced in fresh vs salt water??
