How many colours is sunlight made up of?

Answer 1

sunlight contains all the visible wavelengths of the electomagnetic spectrum. The spectrum of visible light to the human eye is 380nm to 780nm. All visible colors exist in this range. There is no certain number of colors. You must think of it more in terms of wavelengths. Whatever wavelength is reflected is the wavelength you see with your eye. But sunlight contains all visible light, therefore all visible wavelengths, and therefore all visible color.

Answer 2

Colors In Sunlight

Answer 3

Usually people will say that there are only seven colors in sunlight; Red, Orange, Yellow, Green, Blue, Indigo, and Violet. It's the whole ROYGBIV thing.

The truth is that there are many, many colors. If you look at a rainbow, do you ever see solid bars of color? No. In between yellow and green, there's yellowgreen. Between yellowgreen and green, there's GREENISH yellowgreen, and so on. The blended areas between the stripes make up a very large myriad of colors, the number of which we may never know for sure.

Answer 4

According to astronomers and physicists, sunlight is made up of a spectrum of colors. The color spectrum has the same colors as a rainbow: red, orange, yellow, green, blue and violet. When all these colors are blended together they make white light

Answer 5

I agree with Anon E Mouse. 7 traditional visible, plus invisible infre-red and ultraviolet, but infinite shades in between.
The interesting thing is, when you add the different colours of light, you get white, because light is additive, but when you add different colours of paint(red, blue, yellow or orange, green, purple for example) you get brown, because pigment is subtractive(it subtracts different wavelengths from the white light illuminating it.). Rainbows result from the components of white light being refracted at different angles by the water droplets. The second fainter rainbow, has the colours reversed. A circular rainbow can be seen in the clouds from a plane, circling the plane's shadow.
TMI?

Answer 6

A lot. :)

Sunlight has the entire visible range, plus light that we can't see.

If you split up light using a prism, you can see a smooth red-orange-yellow-green-blue-purple rainbow.

Historically, sunlight has been referred to as having seven colors: red, orange, yellow, green, blue, indigo, violet. In reality, though, the actual number of colors is nearly infinite.

Answer 7

Sun light contains almost all frequencies of the electromagnetic spectrum. In the visible spectrum, between the infra red and ultraviolet, all the seven colours Violet, indigo, blue, green, yellow, orange and red are present.

Answer 8

Sunlight is a continuous spectrum, so you could say the number of colors is infinite. Saying that it consists of six or seven colors is just a simplification. There are no sharply defined color bands. So between red and orange, for example, there are all shades of reddish-orange and orangeish red.

Answer 9

Define colour? The sun is a blackbody radiator and as such emits a continuous spectrum from gamma rays through the visual spectrum to radio waves.

Answer 10

all of the visible colors are present in sunlight
