What is shadow?
Is it mater or non-mater?
Answers
Answer:
To really understand what a shadow is, we really have to know what a shadow is not. When we look around, we see objects because light is bouncing off of them and that light is hitting our eyes. When something blocks the light that would shine on an object, there is a shadow. This is because a certain area has no light hitting it, and so no light can be scattered off of it for us to see.
Matter is usually defined as something that has mass and takes up space. So a shadow is not matter, since it has no mass and takes up no space. Instead, a shadow is a lack of light on a certain area.
non mater
Explanation:
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.
