WebIn physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. [1] Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. WebThis assumption is based on the premise that maximum downward refraction of sonic energy will occur at the depth of the strongest minimum sound speed gradient, thus causing short horizontal sonar ranges. The depth of the bottom of the surface layer of water is a great determinant of sonar performance from a hull-mounted surface-ship sonar ... duke raleigh hospital emailhttp://hyperphysics.phy-astr.gsu.edu/hbase/Sound/refrac.html duke raleigh hospital careers
