Do we need shadows?

Shadows are important historically, for they provided early evidence that light travels in straight lines. Humans constantly, but unconsciously, use shadows to judge the shape of objects in their environment.

Why do we have shadows?

Shadows are formed because light travels in straight lines. 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.

Why there is no shadow of light?

Since light consists of photons, which are bosons, and because light carries no electric charge, light never directly interacts with other light. So no, light itself cannot directly block other light and therefore cast a shadow. In other words, photons do not bounce off each other or deflect each other.

Is shadow important to us why?

Can fire have a shadow?

Note that fire can have a shadow not because the incoming light beam scatters off the light in the flame. On the fundamental level, one beam of light cannot directly interact with another beam of light. Fires can have shadows because they contain hot air and soot, and not because they contain light.
