The shadow can be seen only on a screen. The ground, walls of a room, a building, or other such surfaces act as a screen for the shadows you observe in everyday life.
Answer:
A shadow is a dark (real image) 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.
Example:-
- Shadows of visitors to the Eiffel Tower, viewed from the first platform.
- Park fence shadow is distorted by an uneven snow surface
