When a light source is blocked by another object, the shadow is formed. A shadow is an area that is deprived of light because the object obstructs the path of light rays from the source. The behavior of shadows can be understood based on the principles of light and the interaction between light and objects.
When light rays from a source, such as the Sun or a lamp, encounter an object, they can be absorbed, transmitted, or reflected. If the object is opaque (does not allow light to pass through), it blocks the light, creating a shadow on the Shadow and Reflection opposite side. The shadow appears on surfaces that are not directly illuminated by the light source.
The shadow's characteristics depend on several factors, including the shape and size of the object casting the shadow, the distance between the object and the surface where the shadow falls, the distance between the object and the light source, and the properties of the light source itself.
The shadow's shape is determined by the shape of the object casting the shadow and the direction of the light source. If the object has a complex shape with multiple angles and edges, the resulting shadow may be distorted or have a different shape compared to the object itself.
Additionally, the distance between the object casting the shadow and the surface where the shadow falls affects the shadow's size and sharpness. As the distance increases, the shadow becomes larger and less defined. Conversely, when the object is closer to the surface, the shadow appears smaller and sharper.
Moreover, the distance between the object and the light source impacts the shadow's size and intensity. If the light source is relatively close to the object, the shadow will be larger and darker. Conversely, if the light source is farther away, the shadow will be smaller and lighter.
In summary, when a light source is blocked by another object, a shadow is formed on the opposite side. The shadow's characteristics, such as shape, size, and intensity, depend on various factors including the object's shape, the distance between the object and the surface, the distance between the object and the light source, and the properties of the light source itself.
