I mean most people think that it's just "red orange yellow green blue indigo violet" right!? But how do we know that it starts at red!.!.!.I mean couldn't it go from cold to warm and like start at violet!? Or yellow!?!?!? Where does the rainbow begin!?!Www@QuestionHome@Com Best Answer - Chosen by Asker: Well, arguably, it goes the other way!. But, certainly it doesn't start at yellow!.!.!. The visible spectrum of light is as follows: violet 380–450 nm blue 450–495 nm green 495–570 nm yellow 570–590 nm orange 590–620 nm red 620–750 nm Where the numbers on the right are the wave length of the light!. As light is refracted, that is to say that a light wave changes mediums thus causing it to "bend" (change velocity), a whole range of wavelengths are created!. However, the human eye can only detect the ranges shown above!. Greater than 750 = infrared where as less than 380 is ultraviolet!.!.!. which you've probably noticed we can't see!. So!.!.!.!.yeah!.!.!. the order is determined by the wavelength in the visible spectrum!. The direction we think of it in seems to me to be arbitrary!. Probably too serious an answer for a random question - but, that's my take!.Www@QuestionHome@Com One only needs to look at a real rainbow and see that, depending on whether you start at the inside or the outside of the arc, it MUST start at, either, red or violet!. A rainbow can not start at yellow!. As far as "starting" at the warm end, it doesn't!. But, somone invented a Mnemonic about "Roy G!. Biv," so it has become tradition to start with Red!. Besides, if one goes by the frequency (or, more properly, the wavelength" of the colors, red is a lower wavelength (the first visible color after infrared) and violet is a higher wavelength!. (just before ultraviolet) So, lower to higher, just like the way we learned to count!. Get it!?Www@QuestionHome@Com Color can be defined as the small spectrum of light energy that we can actually take in with our eyes!. Human beings are only capable of seeing limited number of colors!. The rain drops act as prisms, breaking up the light into what we perceive as the rainbow segments!. The arrangements of colors never change because the light energy is always constant!. There are other colors that we humans can not take in without mechanical assistance; ultra violet and infra red!.Www@QuestionHome@Com there's a key to that!. here's the sequence of colors!. ROYGBIV Red Orange Yellow Green Blue Indigo Violet they started as a ray --all of them together!.Www@QuestionHome@Com Couldn't answer your question, so I gave you a star instead!. I think answer number one pretty much explains it for me!. Good Question!Www@QuestionHome@Com |
