When light cannot pass through an object, a shadow is formed. Shadows are created when an object blocks the path of light, causing the area behind the object to appear darker.
The shadow of an object is formed on the opposite side of the light source because the light rays get blocked by the object, preventing them from reaching the surface where the shadow is formed. The shadow is cast in the direction where light cannot pass through the object.
Depends on the surface of the object that the light is projected on. If the object has a polished surface like an inoxidable steel, or the object is a mirror, the light will produce a reflexion or the light comes back when it hits the mirror. Behind any object, is formed a shadow, since such object is not a glass.
When light cannot travel through an object, it is usually because the object is opaque. This means that light is either absorbed or reflected by the object, preventing it from passing through.
The shadow of an object is formed in the direction opposite to the light source because the light rays that illuminate the object cannot pass through it, creating an area of darkness behind the object where these rays are blocked. This results in the shadow being cast in the direction away from the light source.
A shadow is formed when light is blocked by an opaque object, preventing the light from passing through the object. Shadows are created when an object comes between a source of light and a surface, causing the light to be obstructed and cast a dark silhouette of the object.
