why do we see colours?

Answer 1

Due to specialized cells within the retina of the human eye called rods and cones which can split the spectrum of visible light into its respective individual wavelengths.

Answer 2

Well, the root of this lies in Quantum Mechanics. As we know (if we have studied a bit of physics) that light consists of packets called quanta. Light travels from its source in the form of wave-particale dual nature. That is why we see a pattern on a screen if light is allowed to pass through two holes on an obstructive wall. The wave particle duality also means light has certain wavelengths. In the same breath, we can say white light has certain wavelenth which is a combination of many wavelenths representing seven basic colors VIBGYOR.

So the reason we see colors is that, when white light falls on an object, depending upon the chemistry of the object, certain wavelengths belonging to certain colors shall be absorbed by the object. The reflected light falls on our eyes and it contains only the combination of those wavelengths which are not absorbed by the object that we see.

Answer 3

Our eye contain a screen called retina which contain rod and cone cells.cones are light differentiating cells where as rod cells are sensible to only bright or dark colour. we can only see things whe light reflected from the substances and falls on our retina.
The colour of a substance is due to the colour reflected from it.

Answer 4

Well it's a little different over there in the UK, but here in the US the sunlight contains all the colors. However, all the colors are absorbed by a particular colored object except the one you see which is reflected to your eyes. So the color white is generated by an object that reflects all the colors of the white sunlight to your eyes and the color black is generated when all the colors are absorbed by an object (etc). How's the weather over there? Raining again?

Answer 5

There are several reasons.
The first is the way the human eye is designed. Inside of the eye, there are receptors called cones and rods. Cones see color, and rods see black and white, so to speak. They regenerate themselves constantly. There are more rods than cones.
Second is the light sepctrum. There are different speeds for different colors; for example, purple 'moves' the fastest, while red 'moves' the slowest.
I would suggest you take a look at a website like www.howstuffworks.com for more detail. :)

Answer 6

Each substance reflects light or lights of particular wavelengths and absorbes the rest. 'Colour' is the common name given to 'a set of particular experiences' of human beings caused when light of specific wavelengths fall on their retina. Retina reacts in a specific manner when light of specific wavelength falls on it and the brain interprets it in a specific manner. We have named these experiences as 'Red', 'Blue' etc.

Answer 7

we see colours bcoz.....um............yeah right.ever heard of the prism experiment of the great newton.it states that when the white light falls on a prism it divides into 7 colors vibgyor.the colours which the object absorbs becomes it colors.

Answer 8

light reflects off of them to our eyes

Answer 9

coz u have eyes....! kiddin... god wants us to see and feel everything in life like happinesss=white, darkness=black,angry=red,sweet=pink... etc etc... wanna more ask again...

Answer 10

So I can paint better pictures??.......hehe
