Well basically , it is a shadow because you see when something is blocking the sun what do you see..? Nothing , just a dark area. So the scientific reason for this is basically a shadow!
I believe that is called 'shadow' or 'shade'.
A shadow is the term used to describe the dark area that appears when light is blocked by an object.
Shadow
I don't know if I have misunderstood this question, but dark is the absence of light. The only darkness that I can think of which is made by light are shadows, when light rays are blocked by an opaque object.
A shadow is an area where light is blocked by an object, resulting in a darker region behind it. Shadows are created when an object obstructs the path of light, preventing it from reaching a surface. This causes the surface behind the object to appear darker in comparison to the surrounding areas that receive direct light.
A shadow is made of light, as it is created when light is blocked by an object, causing darkness where the light cannot reach.
Light doesn't reach that deep. It is absorbed and blocked by the water.
light area
blocked by an object, resulting in the area behind the object being darker due to lack of light.
A shadow is a dark area or shape produced by an object blocking light. Shadows are formed when light is obstructed by an opaque object, preventing the light from reaching a surface and creating an area of darkness behind the object.
The dark shadow cast by the Earth on the Moon during a lunar eclipse is called the umbra. This is the central and darkest part of the shadow where the light from the Sun is completely blocked.
An object shadow is a dark area created on a surface when light is blocked by an object placed in its path. The size and shape of the shadow depend on the angle and intensity of the light source, as well as the distance between the object and the surface.
