Same as Differentiation
"The change of direction of propagation of any wave phenomenon occurs when the wave velocity changes. The wave velocity changes when the medium through which the wave travels becomes either denser or thinner, as when a sound wave goes through the air and into a wall or other object." McGraw-Hill Concise Encyclopedia of Science & Technology

"As density increases, we know that pressure increases. As all potential resists passage through it with a strength which varies with its voltage pressure? or density, and as a liquid is a more dense high potential than the air, the water bends the light which reflects the image of the stone to the surface of the pool in a violent curve, then from there to the man's eyes in an immeasurably slight curve. The man does not actually see the stone, nor the position where the stone lies. He sees only its projected image and its position in Nature's mirror." Russell, Genero-Radiative Concept
