what is darkness &where it disappere in front of light?

Answer 1

Darkness is the absence of light. Scientifically it is only possible to have a reduced amount of light. The emotional response to an absence of light has inspired metaphor in literature, symbolism in art, and emphasis.


Darkness, in science, is a relatively low level of light.

A dark object reflects fewer visible photons than other objects, and therefore appears dim in comparison. For example, matte black paint does not reflect visible light and appears dark, but white paint reflects all visible light and appears bright.

However; light cannot simply be absorbed without limit. Energy, like visible light, cannot be created or destroyed. It can only be converted from one type of energy to another. Most objects that absorb visible light reemit it as infrared light. So, although an object may appear dark, it is likely bright at a frequency that a human being cannot see. For more information see thermodynamics.

A dark area has few, if any, light sources present, making everything hard to see, like at night. Exposure to alternating light and darkness (night and day) has caused several evolutionary adaptations to darkness. When a vertebrate, like a human, is placed in a dark area, its iris dilates, allowing more light to enter the eye and improving night vision.

The scientific definition of light includes the entire electromagnetic spectrum, not just visible light, so it is physically impossible to create perfect darkness. For example, all objects radiate heat in the form of infrared light and gamma rays, extremely high frequency light, can penetrate even dense materials.


As a poetic term, darkness can also mean the presence of shadows, evil, or depression.

Darkness can have a strong psychological impact. It can cause depression in people with seasonal affective disorder, fear in nyctophobics, comfort in lygophilics, or attraction as in gothic fashion. These emotions are used to add power to literary imagery.


Artistically, darkness can also be used to emphasize or contrast with light.

Answer 2

Jeremy F is correct, except on one point: light (visible electromagnetic radiation) can actually travel through darkness without being visible. Consider a flashlight in a dark room. You can see the source, and you can see the spot on the wall, but (unless there's plenty of dust) you cannot perceive the beam unless the light is trained on your own eyes.

Likewise in space, which (in our solar system) light permeates, yet a person outside of our atmosphere, in full light of the sun, can perceive the stars, and most of the visible area would appear dark (as a night sky). Thus, darkness is not merely the *absence* of light, but more specifically the absence of light received by our eyes (retinas). Darkness appears to us
1) where there is no light
2) where there is light, but none is reflected toward our eyes

Answer 3

darkness is when the world rotates.. i think hehe and another part of the world has light and the world blocks the light from getting to us on the other side.. leaving us in the dark

Answer 4

darkness is the absence of light.

light produces photons which are reflected off objects and detected by your eyes.

so when no photons are reflected your mind registers it as darkness.

Thereby some people have better night vision than others

Answer 5

It disappears to the extent light appears.

Answer 6

darkness is the absence of light. when your eyes cannot perceive light it show up that void as darkness.

Answer 7

you can have many scientific answer but the fact is that darkness always existed ... it never dissappeared or went anywhere and will always exist forever... its the light that came in its way and destroyed it ...

Answer 8

darkness is a lack of light,light is a lack of darkness.

Answer 9

nothing is this both just like tail and head of a coin when tail is there than head is not there and when head is there tail is not there and u can't see both one at a time

Answer 10

Lights do not emit light, they suck dark.
