The amount, or degree, of refraction is related to the difference between the speeds of light in the two materials of different densities—the greater the difference in densities, the more the speed changes, and the greater the bend. A slanting object partly out of water displays refraction.

Web28. feb 2016 · What we are seeing here is a physics concept called refraction, or the bending of light. When light passes through transparent objects (in this case, the front of the glass, the water, and the back of the glass), it refracts or bends. When the glass is full of water, it acts as a cylindrical convex lens, and produces an inverted image. WebRefraction is the change in the speed of a wavelength while it passes through a material.
