 Of two substances, the one which has the greater absolute index of refraction is said to be the more dense optically. When a ray passes from a less dense to a more dense medium, it is bent toward the normal as shown in...

...light to pass from one medium (such as air) through another medium (such as water or a lens). As the light passes from a less dense to a more dense medium it is bent, or refracted. A visual example of this phenomenon is looking at a teaspoon in a clear glass of water. The teaspoon... | |
