Nature of Light: Characteristics of Light (first in series)

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the first of four Science Objects in the Nature of Light SciPack. It establishes the concept that electromagnetic waves can interact with materials in different ways. For example, they can reflect off a material’s surface. We can see an object when light waves that are emitted or reflected by the object enter the eye. Electromagnetic waves can also pass through materials, sometimes slowing down or changing direction as a result of entering and leaving the material. Or, electromagnetic waves may be absorbed or scattered within the material. Electromagnetic waves and other waves diffract around corners, and interfere with one another in predictable ways.
