the colours were already in the white light.
Newton Discovered that White light comprised of the entire spectrum of the visible wave length. When white light was shone through a triangular prism, it refracted the entire color spectrum.
a prism, and the telescope
Violet light does not split into different colors when it passes through a prism.If it goes in violet, it comes out violet.White light is a combination of light of many colors. If you pass white light througha prism, a spread of different colors will come out of the prism, because each colorbends through a slightly different angle on its way through the prism.
Newton in the year 1666 , also he said that colours were not introduced by the prism ,but they were components of white light.
Refraction
Newton Discovered that White light comprised of the entire spectrum of the visible wave length. When white light was shone through a triangular prism, it refracted the entire color spectrum.
That was discovered by Sir Isaac Newton.

a rainbow of colors
Isaac newton
When the colors formed by a prism is made to pass through a second prism, it results in producing white light. Newton's experiment demonstrated in this method is recombination of light. Conversely dispersion can be demonstrated with the help of a single prism.
Newton
Newton demonstrated this with his prism.
Newton showed that light was made up of all the visible colors by breaking it up with a prism.
in 1665 when Issac Newton placed a triangular prism on his desk and saw that it shined out the colors of the rainbow
hook and newton. Issac newton first solved the puzzle correctly. he worked out that ordinary whit light contains all colors of the rainbow . he set up a demonstration to show that his ideas were right and that another scientist,RobertHookewas wrong . Hook's ideas was that a prism colors the light. Newton shone a narrow beam of ordinary light on toa prism. He saw arainbow of colors coming from the gall. Then he blocked out all the colorsexceptfor the blue light and passed this blue light through a second prism. If hook was right , the second prism would re-color the bluelight. But as newton showed it didn't. The bluelight stayed blue. It was just as newton demonstrated, a prism splits up the colors, And then blue lightpassing through a prism stays blue and red light stays red. Newton's idea that lightcontainsas school. It is hard to imagine that scientist once doubted it. we also now that, as Newton demonstrated, if you add together light of all the colors, the result white light.
He discovers what is known as the rainbow, by using a prism to show that light is made up of all of those colors.
