Just as sound waves interact differently with different media, so does light. Some of the light energy that reaches an object is absorbed by the object. We usually see these as dark things. For example, a black pair of jeans absorbs more light than a white shirt, which reflects light. Objects that reflect more light tend to be white or light colored objects. Often we tend to wear darker colors in winter because they absorb more of the sun’s rays, keeping us warmer. Wearing lighter colors in the summer helps keep us cooler, as more light rays are reflected away from our bodies.Some objects (such as glass) allow light to pass through them instead of reflecting light. These objects are transparent because they transmit light. Transparent objects can reflect light, as well, just as some light reflects off glass, to give us glare. Materials that allow just a very little bit of light to pass through them are called translucent materials. A translucent material diffuses the light rays so you can’t see a clear image of the object that is behind it.
Other materials block all the light hitting them. These are called opaque materials. Metal and other materials you cannot see through are opaque. Opaque objects can reflect and absorb light, but they do not transmit light.
