What is a shadow? Explain by giving an example.

Shadows are made by blocking light. Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object. The dark area is called a shadow

An example of shadow is a faithful dog that follows behind you all day.
