Light is a form of wave energy.
Waves the can move through space are called electromagnetic waves.
Waves that moves perpendicular to the way that the matter is moving are called transverse waves.
The height of the wave is called amptitude
The number of waves in a second is called frequency
Speed refers to the distance that one wave travels in a second
The different colors of light is called visible spectrum
Light can also change direction by reflection. Reflection happens when light bounces off an object.
Colors that cannot be made by other colors are called primary colors
Opaque substances use to color other materials are called pigments.
