These objects are opaque.
The light from its source is reflected by the objects into our eyes. Light travels in a straight line; therefore, when its path is blocked, it will change directions.
By shining light on other objects.
Light is blocked by light form
A Shadow is the absence of light next to an area of light. The absence of light is caused by an object that is in the direct path of light so that light cannot reach the area that the shadow is in. Light cannot go around an object and is therfore blocked by objects creating an absence of light that is proportional to the object that is blocking the light.

I think this is basic science. The light from its source is reflected by the objects into our eyes. Light travels in a straight line therefore, when its path is blocked, it will change directions.

Perhaps a better question is "why would it be?" Bright objects are the way they are because they emit light (and other electromagnetic energy). We are not living in a cosmic fog, so light reaches earth and we can see stuff. Isn't that great?!
collects light from other objects like the moon.
Shades are created when an object blocks light from a source, casting a shadow. This can happen with opaque objects that do not allow light to pass through them, creating a dark area behind them where the light is blocked. Shades are also created when objects absorb or reflect light in a way that creates areas of darkness.
Infrared light can be blocked by the same opaque material that can block any other color light. Just because we can't see it doesn't give it any special penetrating powers.
when objects get lighted from other source of light it is known as illumination
Non-luminous. Objects which produce light of their own or give out or emit their own light are called luminous objects. Objects which do not produce light of their own, on the other hand, are called non-luminous objects. Luminous objects are objects like stars, sun and other celestial bodies which give out their own light. Objects surrounding us are not such light emitting objects. Therefore, we are surrounded by non-luminous objects.
