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
What else can I help you with?
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.
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
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.
What separates visible light into is many colors by bending each wavelength at a different angle?
A prism separates visible light into its different colors, as it is made up of a transparent material that causes light to refract at different angles depending on its wavelength or color. This phenomenon is called dispersion, with shorter wavelengths (like blue) bending more than longer wavelengths (like red), creating a spectrum of colors.
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.
Are there only seven colors of light?
No, there are actually infinitely many colors of light. The colors that we see are a small portion of the electromagnetic spectrum, with each color corresponding to a different wavelength of light. The visible spectrum consists of colors from red to violet, but there are many other colors that are outside of our visible range such as ultraviolet and infrared light.
Is ordinary light one color?
No. White light is a mixture of many colors. When you see a rainbow, you see the white light separated into its components.
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
How many colors are in the visible spectrum?
There are seven colors in the visible spectrum: red, orange, yellow, green, blue, indigo, and violet.
How many colors are in the spectrum, and what is the significance of this range of colors?
The spectrum consists of seven colors: red, orange, yellow, green, blue, indigo, and violet. This range of colors is significant because it represents the different wavelengths of visible light and how they combine to create the full spectrum of colors that we can see.
How many colors does white have?
white contains all of the colors black reflects all of the colors
How many colors are in a spectum?
A spectrum contains an infinite number of colors since it is a continuous range of wavelengths of light. However, the visible spectrum typically consists of the colors of the rainbow, which are red, orange, yellow, green, blue, indigo, and violet.
How the color white is made up of many colors?
White light is composed of all the colors in the visible light spectrum. When white light passes through a prism, it is refracted and separated into its component colors, creating a rainbow. Each color in the spectrum has a different wavelength, and when combined together, they form white light.
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.
How many colors are there in the color spectrum?
There are seven colors in the visible color spectrum: red, orange, yellow, green, blue, indigo, and violet.
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.
What object separates white light into many different colors?
A prism separates white light into its different colors by refracting or bending the light at different angles depending on its wavelength. This dispersion of light reveals the visible spectrum of colors ranging from red to violet.
