fastest colour???

David

Dealers ALWAYS lie.

Everyone knows blue ones are fastest

Always said yellow - black is the new yellow...

BLOO

[SoulKiss]

Nah, Red is faster thats why.....

Chuck Norris rides a Red SV

Blue

You mean black AND yellow

Its blue BLUE BLUE

Light travels the same speed through a vacuum at all wavelengths, but when we send the light through something other than a vacuum, like glass we see that light bends/slows, this is seen through Snell’s law below

n1*sin(theta1) = n2*sin(theta2)

the part in the equation n1 & n2 are called the index of refraction, it is the ratio of the speed of light in a vacuum divided by the speed of light in that substance, so an index of refraction of 1 means that you are in a vacuum b/c the speed of light travels the same speed it would in a vacuum. But if you send light through water, water has an index of refraction and light slows down. The process of light slowing down bends the angle at which the direct ray of light travels, so the MORE light slows down the MORE it bends, now say you have a drop of water suspended in a vacuum above your head, white light (which is composed of all frequencies of visible light) hits this clear drop of water and is slowed down and bends, but the different frequencies of light that compose the white light bend different amounts (this amount is small but visible from a distance) the lower frequency light is less affected by the drop of water as it has a longer wavelength and oscillates a lesser amount of times through the distance of the water drop, the higher frequency light oscillates many times through the same water drop and is slowed down more because of it so it bends more. This process is called diffraction and causes the spectrum of colours in white light to diffract when sent through matter. The blue light (higher frequency) is bent more and the red light is bend less and through this distance of bending is a gradient of light that we call a rainbow.

So to answer your question, the speed of light is the same for all frequencies in a vacuum BUT when you send light through matter is slows down a certain amount, red light (lower frequency) travels faster than blue light (higher frequency).

The lower frequencies are affected less by travelling through matter, this is why infrared light is used in fibre optics as opposed to ultraviolet or visible light.

So based on your theory then, in decending order of fastnest

Red
Orange
Yellow
Green
Blue
Violet

That still doesn't account for black, which is the absence of all light, therfore will not be affected at all. ergo Black is the fastest

I bought a black one, so black gets my vote.
