In science class you're usually taught 7: red, orange, yellow, green, blue, indigo, and violet.
In my opinion, "indigo" is not really a color, it's just "that part of the spectrum where we're not quite sure if it's blue or violet." Cyan is a much more distinct color than indigo is.
Beyond that, it's really a matter of where do you stop counting. I could see a case for six (the listed ones minus indigo) or eight (the listed ones plus cyan).
The eye is capable of distinguishing perhaps ten million colors, but some of those don't appear in the spectrum (brown, pink, dark green, magenta). I don't think anyone has ever bothered to enumerate how many distinct (in the sense that a person could say "A is not the same color as B", not in the sense of having actual names as opposed to "greenish-yellow, but a little more yellowish than that last one") colors appear in the spectrum

Which part of the em spectrum is visible to the human eye?
Many particle physicists, radiation specialists, opticians and ophthalmologists have gotten togetherand named that part of the spectrum the "visible light" band.
Which color has the longest wavelength?
Of the colors in the visible spectrum, red has the lowest frequency and the longest wavelength. As you move on "up" the spectrum, wavelengths get shorter.Red has the longest spectrum of all visible light. But infrared is even longer and there are many more "colors" but you can't see them.
Why does the colors of an object look different under a fluorescent lamp from the way it looks under an incandescent lamp?
differences in the color of light will change the color's appearance as it is seen under fluorescent and incandescent. An incandescent lamp, like the sun, produces a spectrum of light in every color in a wide band, broad enough to cover the entire visible spectrum -- and extending past it to many colors that humans can't see. A fluorescent lamp produces a spectrum of light in a few narrower bands of color. That is why a fluorescent lamp is more energy efficient than a incandescent -- the fluorescent lamp doesn't waste energy producing photons that humans can't see. Some materials (such as white paper) reflect all visible colors equally. They look white in almost any kind of light. Other materials absorb some colors more strongly than other colors. They look colored in "white" incandescent light. If we have a material that reflects most colors equally, except for a narrow band of colors, and that band is in the "dark" part of of the fluorescent spectrum -- it will look the same color as white paper. If we have another material that reflects most colors equally, except for a narrow band of colors that is in one of the bands of colors produced by a flourescent lamp -- that material will look even more deeply colored in fluorescent light than in incandescent light.
What separates visible light into is many colors by bending each wavelength at a different angle?
Prism
What are the colors of visible light and how can you see them?
light is invisible you can only see the things it bump in to... and when you're saying visible light i think it 's only lasers who fits that description and they are many different colours
Why do the colors of the visible spectrum exist?
because light is made of many colours and when it hits a serten object the light seperates
Is White light is made up of an mixture of many colors of light?
White light is what we see when light of all (or most) of the frequencies in the visible spectrum are emitted together from the same source. It is the combination of every visible light wave.
Why are flies attracted to yellow colored items?
The vision of flies does not capture the entire visible light spectrum. Many flies see colors as shades of yellow and blue which is why they are attracted to these colors.
How many colors are actually in the world?
There is essentially an infinite about of colours which can exist on the visible light spectrum. Every possible variation and shade could be considered a different colour.
Which part of the em spectrum is visible to the human eye?
Many particle physicists, radiation specialists, opticians and ophthalmologists have gotten togetherand named that part of the spectrum the "visible light" band.
The entire range of em waves is called the?
The total of all electromagnetic waves is called the electromagnetic spectrum. The electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visible light waves, ultraviolet radiation, x-rays, and gamma rays. Only visible light waves, which humans see as the band of colors from red to violet, are the portion of the spectrum visible to the human eye, although many other life forms are sensitive to infrared and possibly to other segments the spectrum.
How can you show that visible light is made up of many different wavelength?
A prism will separate visible light into its component colors.
What are ultra violet rays?
White light, like sunlight, is made up of many different colors of light. We see this when raindrops split the light into a rainbow. The purple part of a rainbow is violet light. Some parts of the light spectrum are not visible to the human eye. The invisible part next to purple (violet) is called the ultraviolet spectrum.
What is a sort of device is commonly used to separate the colors of light from white light?
One device that splits white light into the colors of the visible spectrum is called a prism. It is a triangular piece of glass through which a narrow band of white light can pass. The blue color light is bent most, and the red color light bent the least. So the colors in-between red and blue are seen on a screen as a spectrum. A rainbow is produced when drops of water in the sky have light passing into them, and the light is bent in a similar way, producing the spectrum. So there are many devices that can produce a spectrum of the colors.
Which color has the longest wavelength?

A is an object that separates visible light into the many different colors the light is made up of?
i think its a prism
