why are the rainbow colors ROYGBIV so different and not 'blended' form one end of the range to the other

Question

e.g. like yellow, orange, red, green/ blue violet and indigo

delete 'form" and substitute 'from'.
thank you!

Answer 1

Interesting question.
Obviously to do with the way we perceive wavelengths. Can it be that the speed of light varies from one wave form to another. If so how would this reconcile with the concept
of light having mass? Would each 'color' be of different mass?

Answer 2

Wavelengths of light that produce color are caused by electrons jumping orbit which cause a specific wavelength of light. Different orbit jumps produce different colors. So there isn't any between colors produced because there are no obit jumps that produce in between wavelengths of color.
When white light which is a blend of all colors goes through a prism it is divided up into its different wavelengths. Red light because it longer is changed in direction the most so it is on one end of the spectrum. Violet is the shortest visible light so the prism can change it direction the least. So it is on the other end of the spectrum. If light could be produce in any wavelength like sound waves then there would be a blending. But unlike sound waves light only comes in distinct wavelengths. Its like making music with distinct notes with nothing in between. You realize the eye can only see red, yellow, and blue. So orange and green are blends of the colors on each side of it. There is no orange or green light. Those colors were made up by the brain by blending two colors together.
As a side note there is no such thing as color in the real world. There are electromagnetic waves in the real world which vary in wave lengths. Some we can see and some we can't. The brain has three color receptors that pick up certain electromagnetic waves and interprets them as color.
The electromagnetic waves do not have colors. But the brain needs a way indentify a wave length so it attaches a color to a wavelength. In other words the brain produces color. Nature produces electromagnetic wavelengths.

Answer 3

A better question would be: why are there so many colors that our eyes can't see if they were made by intelligent design.

Answer 4

ROYGBIV is just an mnemonic to help people remember the principle hues of the visible light spectrum. It also helps people remember which order the colors go in the visible light spectrum.
