When I ask "what's the opposite of light", what's the first answer that comes to your mind?
middlj said:The question doesn't make sense to me unles you take "light" as an adjective. So the only two answers it could be is dark or heavy.
I don't think you can have an opposite of an object?
pergradus said:in my mind "opposite" means the sum of two things add to zero.
So my definition is correct
Dadface said:(All experiments on light must be done in the dark.Was it that geezer Goethe who said that?)
Pythagorean said:criticism and skepticism that light has an opposite in the first place.
Darkness is the absence or lack of light. It is the opposite of light and is characterized by the absence of color and brightness.
Darkness is created when there is no source of light or when light is blocked or absorbed by an object. It can also be created by the rotation of the Earth, causing the absence of sunlight during the night.
Darkness can have different effects on different organisms. Some animals, like nocturnal creatures, are adapted to thrive in darkness. However, prolonged exposure to darkness can disrupt the circadian rhythm and lead to sleep disturbances in humans.
Yes, darkness can be measured using a device called a lux meter. This measures the amount of light in a given area and can determine the level of darkness. Darkness is measured in lux, with 0 lux being complete darkness and 100,000 lux being equivalent to sunlight.
While darkness is necessary for certain organisms and can have benefits such as regulating sleep and hormone production in humans, it is not necessary for all forms of life. Plants, for example, require light for photosynthesis and cannot survive in complete darkness.
