Reflection, Refraction and Absorption
Reflection: When light is reflected, it bounces back from a surface. Reflection allows objects to be seen that do not produce their own light. When light strikes a smooth, shiny object, it is reflected so that can image can be seen. For example, a mirror or a pool of water will reflect (bounce back) and image very similar to the object.

Refraction: When light is refracted, it passes from one type of transparent material to another, and changes direction. For example, when light travels through a magnifying glass, it changes direction, and we see a larger, magnified view of the object. When a straw is view in water, light passes from the water to the air causing the path of the light to bend. When the light bends, the straw appears distorted (bent or broken).

Absorption: When light is absorbed it does not pass through or reflect from a material. It remains in the material as another form of energy.
Seeing Color:The light that is reflected by an object determines the color(s) of that object. Color is NOT caused by the absorption of light by an object. For example, a red object reflects red colors of light and absorbs all other colors. Color is seen when all of the colors of light are absorbed. The color white is seen when all of the colors of light are reflected. The color black is seen when all of the colors of light are absorbed. |
