When viewed under white light, it appears red. But this does not mean that emits red light, which would be the case an additive synthesis. Doing so, we would be able to see in dark. Instead, absorbs some wavelengths that comprise the white light, reflecting only those human seen as red. Humans see red apple due to the particular operation of your eye and brain interpretation of information coming at you in eye (advanced color theory).
The reflected waves are captured by the eye and interpreted in brain as different colours depending on the lengths of corresponding waves. The human eye can only perceive wavelengths when light is abundant. In low light is in black and white. In so-called additive synthesis (commonly called "colour overlay light") white colour results from the superposition of all colours, while black is the absence of colour.
In other words, these cells are excited or inhibited at the higher signal intensity versus Red Green and Blue to sum of Red and Green, also generating an achromatic path information related to luminosity. The information in this processing moves through the optic nerve to lateral geniculate nucleus (located on the left and right thalamus), where neuronal activity specific regard to suggestion of colour and chiaroscuro.
The vision is a sense that is the ability to detect light and interpret it. The vision is characteristic of having such a dedicated system she called animal visual system. The first part of visual system is responsible for forming the optical image of visual stimulus on the retina (optics), where the cells are responsible for processing information.
It is called additive to obtain a light colour determined by the sum of other colours synthesis. Thomas Young based on the discovery of Newton that the sum of colours of visible spectrum formed white light conducted an experiment with flashlights with the six colours of visible spectrum, projecting these foci and superimposing reached a new discovery to form the six colours of spectrum only took three colours and also adding the three light formed. Reproduction process normally used additive red, green and blue light to produce other colours. Combining one ofse primary colours in equal proportions with other colours produces secondary additives, lighter than previous cyan, magenta and yellow.
This region, called visible spectrum, includes wavelengths from 380 nm to 780 nm (1 nm = 1 nanometer = 0.000001 mm). The light from each ofse wavelengths is seen in human brain as a different colour. Therefore, in decomposition of white light in all wavelengths by a prism or rain in rainbow, the brain perceives all colours. Therefore, the visible spectrum, which is the part of electromagnetic spectrum of sunlight can be seen, each wavelength is perceived in brain as a different colour. Newton first used the word spectrum (Latin for "appearance" or "apparition") in 1671 in describing his experiments in optics.
Newton observed that when a narrow beam of sunlight incident on a triangular glass prism with an angle, a part is reflected and again passes through the glass and disintegrates in different colour bands. Newton also made to converge those same rays of colour in a second lens to form white light again. He proved that sunlight has all the colours of rainbow. When it rains and the sun shines every raindrop behaves just as Newton's prism and union of millions of raindrops phenomenon arc is formed iris.
This is because brain activity retinal since photoreceptors, although simple, are neuronal cells. Information of rods and cones is processed by other cells located immediately below and connected behind them (horizontal, bipolar, amacrine and ganglion). The processing inse cells is the source of two-dimensional or antagonistic pairs chromatic channels: Red-Green - Blue - Yellow and an achromatic channel dimension or chiaroscuro.
