how do we see color wavelength

We see different wavelengths of light as different colors because the different wavelengths stimulate different cells in the retinas of our eyes. Wavelength as RGB color.

Light Is Made Up Of Wavelengths Of Light And Each Wavelength Is A Particular Colour The Colour We See I Light Science Visible Spectrum Visible Light Spectrum

Infrared light is not visible to our eyes but our skin can perceive it as warmth.

. 400 nm and 780 nm. The wavelengths that we can see with our eyes are between approx. The color we see is a result of which wavelengths are reflected back to our eyes.

What makes color vision possible for humans is the electro-magnetic sensor we call the retina. There is an overlap of the cones sensitivity beyond the three single RGB wavelengths. This overlap along with the brain processing the simultaneous signals sent to it actually allows us to see millions of colors.

Red has the longest wavelength. There are three kinds of color-sensitive cells in our retinas for red green and blue. The colors of the rainbowred orange yellow green blue indigo and violetmake up the visual spectrum of colors.

The yellow color is Hubbles view in visible light. We see them as colors of the rainbow. However colors exist only in the brain and so cannot be directly identified.

The colors of the visible light spectrum are determined by the wavelength of the light. Visible light spectrum wavelengths are used in many different fields including astronomy medicine and communications. Our trichromatic color vision is the result of retinal cells known as cones who have three types of spectral sensitivity for short mid and long wavelengths but it is a well-known fact that the light we see is just a tiny fraction of something much bigger called the electromagnetic spectrum.

Most of this light comes from stars and they trace the same spiral structure as the dust lanes. Our eyes are able to detect how much radiation is entering them and from what direction only if that radiation is within the visible spectrum which is between approximately 380 and 780 nanometers nm. Each color has a different wavelength.

The visible spectrum shows the wavelengths of each of the component colors. The spectrum ranges from dark red at 700 nm to violet at 400 nm. The objects we see around us on the other hand do not shine with their own light and reflect only particular electromagnetic wavelengths from the visible spectrum after.

How do we see color. Different wavelengths of light appear to our eyes as different colors. One way to see this is to shine white light through water.

For example the color yellow results from green and red cones being stimulated together. Violet has the shortest wavelength. These unique wavelengths determine the shades and hues of the colors we see.

It might be hard to imagine but all visible light is made up of the colors of the visual spectrum each color has its own unique wavelength. The best I could do would be to calculate what combination of colored lights or paints will most closely reproduce the save wavelengths and produce the closest colors in the brain. Yellow light stimulates both red and green cells.

Shorter wavelengths appear blue or violet and longer wavelengths appear red. Electromagnetic radiation varying in wavelength from gamma rays to microwaves is constantly bombarding us from all directions. It highlights the heat emitted by dust lanes in the galaxy where stars can form.

So how do we see the wavelengths in-between Red Green and Blue. The red color shows Spitzers view in infrared light. The sensitivity of the eyes receptors to a light wavelength is responsible for color vision.

A spectrometer or spectrograph will identify the wavelengths. The longer-wave infrared radiation starts at wavelengths greater than 780nm. Visible light waves are the only electromagnetic waves humans can see.

We see the waves as the colors of the rainbow. When all the waves are seen together they make white light. UV light which is invisible to us begins at below 400 nm.

Light waves like waves in water can be described by the distance between two successive peaks of the wave a length known as the wavelength. The blue color shows Chandras view in x-ray light. Other colors are perceived through combination.

For example light with a wavelength of 700 nm is red while light with a wavelength of 400 nm is blue. We think that white has no color but that is not true. We can perceive colors in things like crayons and flowers since they reflect and absorb the rays of light that strike them.
