What is the science behind shadow?
Simply speaking, a shadow is the absence of light. Light is a form of energy that travels in a straight line until it hits an object. If the object blocks the light from passing through it, that creates an area of darkness–a shadow–on the other side.
How can you tell where the sun is based on a shadow?
Mark the shadow cast at first light. To get an accurate read on your direction using shadows, you’ll need to first wait for sun to set. When the sun rises in the morning, mark the spot your sun rod casts its first shadow. This shadow will point directly west, no matter where you are on earth.
What is a shadow class 2?

How do you explain shadow to a child?
Students learn that a shadow is made when an object blocks the light. Children make shadows with their bodies and other objects. Children observe that a shadow can show an object’s shape, but it can’t show colors or details (like a smile or a frown).

Shadows are formed when an opaque object or material is placed in the path of rays of light. The opaque material does not let the light pass through it. The light rays that go past the edges of the material make an outline for the shadow.
Do shadows exist?
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.

What is a shadow in physics?
Simply speaking, a shadow is an absence of light. If light cannot get through an object, the surface on the other side of that object (for example, the ground or a wall) will have less light reaching it. A shadow is not a reflection, even though it is often the same shape as the object.
Can shadows exist without light?
If the object they hit is opaque, the light cannot pass through, and a shadow forms. Simply speaking, a shadow is an absence of light. If light cannot get through an object, the surface on the other side of that object (for example, the ground or a wall) will have less light reaching it.
