shadow
Definition
A shadow is an area where light is blocked by an object. It is the opposite of light.
We can see shadows because light travels in straight lines. When an object blocks the light, the light cannot reach the area behind the object. This area is called a shadow.
The size of a shadow depends on the size of the object and the distance between the object and the light source. The closer the object is to the light source, the bigger the shadow will be.
How can the word be used?
