Shadow......
A shadow is a dark area where light from a light source is blocked by an opaque object.
It occupies all of the three-dimensional volume behind an object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.
Light
Speed. The speed of light, which is 300,000 kilometers per second, is held to be the absolute upper speed limit of anything in the universe and the most fundamental property of light.
Reflection. Light particles, or photons, reflect off other particles or masses and continue to travel at the same speed.
