What is Newton's color wheel?
It is a disc that is divided into coloured segments. It can have three segments, each shaded with one of the primary colours red, green and blue, or it can be divided into seven segments shaded with the colours of the rainbow; red, orange, yellow, green, blue, indigo and violet. When you spin the disc rapidly the colours merge to give the appearance of white light. It shows that what we see as white is in fact a combination of all colours.
What were Isaac Newton's discoveries?
Sir Isaac Newton was an English mathematician, physicist and chemist whose many important contributions to science (and discoveries) laid down the foundation for much of the progress in science as we know it. He was a co-inventor of calculus; he unraveled the mysteries of light and optics; he formulated the three laws of motion, deriving from them the law of universal gravitation.

How many colors were used in the bayeux tapestry?

How many Spartans were there for every helot?
Each Spartan citizen was allotted the produce of seven helots to support them. They also took seven helots to war for each Spartan warrior - these acted as light infantry, and at the same time reduced the threat of a helot uprising at home while the Spartans were away. At the battle of Plataea in 479 BCE, there were 5,000 Spartan hoplites (armoured warriors) and 35,000 helot light infantry.
Who discovered white light consists of 7 colours?
Sir Isaac Newton is credited with discovering that white light consists of seven colors by conducting experiments with prisms in the 17th century.
Who discovered that light is made up of 7 colours?
The discovery that light is made up of seven colors was credited to Sir Isaac Newton. He demonstrated this by passing sunlight through a prism and observing the separation of the light into its component colors, creating a rainbow spectrum.
How do different colors appear on CD?
When white light shines on the CD, the light is separated into seven colours, so different colours appear on the CD.
What is the color of light?

What are primary colors of light?
This Q&A is about light colours. Paint colours are substances, and different from light colours.If you hold up a glass prism to a beam of sunlight, you'll see the light form a rainbow of colours. This is called the spectrum. It consists of all the colours that make up "white" light.Although you might be able to see seven colours in the spectrum, the white light is really made up of three basic colours. These are called the primary colours because they cannot be made from any other colours. The primary colours of light are red-orange, green, and violet blue. The other colours you see in spectrums or rainbows are made by a mixture of the primary colours.When the naked eye looks at the spectrum, it can see three mixed colours, which are called secondary colours. The secondary colours in light are green-blue, yellow, and magenta-red. You can produce these colours by mixing the primary colours in certain combinations.
What is the break up of white light into seven colours?
It is the refraction of white light being shone through a glass prism, or a raindrop, that separates the white light into the colours of the rainbow.
How can we split up white light into the seven colours of the spectrum?
Use a prism.
Who discovered white light can split into the seven different rainbow colours?
Sir Isaac Newton discovered that white light could be split into its component colors using a prism. He demonstrated this by passing sunlight through a glass prism and observing the separation of light into the seven colors of the visible spectrum: red, orange, yellow, green, blue, indigo, and violet. This experiment helped establish the foundation for our understanding of light and color.
Why do you get a mirky color and not white when mixing the seven colors of the rainbow?

Why we get brownish icky color and not white on mixing seven colours of rainbow?
Some of the colors are dark. when you mix colors, you usually end up with something darker,or the same color. so in mixing the colors of a rainbow, it would make a darker, (Icky) colorinstead of getting lighter.===============================Answer #2:-- How are you "mixing colors" ? Are you mixing light, or mixing paint ?Mixing paint is not the same as mixing light.-- There are more than seven colors in the rainbow. Every color that youor anyone else has ever seen is in the rainbow, as well as every color ofpaint ever mixed, every color of fabric ever woven or dyed, every color thatcan be produced on the screen of your computer monitor, every color evernamed, and those without names. All are present in the rainbow.-- The combination of all possible colors of light, in the correct proportions,produces white when they enter your eye and "mix" there.
