So Einstein tells us that the speed of light is constant (E=MC2). Which is all very well in theory, but that is in a vacuum and reality the speed of light actually varies according to the density of the medium through which it's travelling. So that includes air, water, glass, diamond etc. Now the visible light spectrum is red through to violet with red being the lower frequency and blue being the higher. This means that the slower end of the frequency range will be affected more by the denser medium. Therefore, if a red and a violet car are racing and appear to arrive at the finishing point at EXACTLY the same time, then in fact the red car has arrived there fractionally before the violet one because it took longer for the image to reach the eye.

 

White cars - dunno how this affects them. As white reflects all colours then they must arrive at different times, be surprised if they don't fall apart with the strain ! ;) However, as they reflect all colours and absorb less then they could end up having less mass ...

 

Silver cars - well sliver is just dirty white - see above

 

Black cars - technically black isn't a colour, I give up. Presume it absorbs more light photons and consequently has more mass than the others - QED, must be slower !

 

 

So, in summary, assuming all things being equal and all cars go the same speed then the violet (well lets say blue, violet is just too gay for a proper car), will appear to arrive first or be faster, according to our normal methods of timing, eg photo-finish etc. The red will appear to be the slowest.

 

 

End of ! :D

You've got far too much time on your hands Andy. Lol.

a lot of thought went in to that lol.

Oh god,

 

This WILL get messy.

WHITE ZED'S ARE FASTEST

I'd agree with that !

It’s not the colour that counts ….. But who’s driving :D

 

(oh and spec, and BHP of the car in question ;) )

actually E=MC2 has nothing to do with the speed of light, it is used to determine the amount of energy that can be obtained from matter.

 

E = Energy

M = Mass

C = Compression (Squared)

 

This is the formula that is used to determine the yield of nuclear weapons (among other things)

 

The speed of light is actually given the constant 'c'

Out of personal experience, red is fastest, black looks best

red is fastest, red looks the best, could enzo ferrari be wrong ;) ,

How come I knew you would say that?

 

....explain honey in english what the hell you are wittering on about :rofl:

 

btw gunmetal grey of course is the fastest :D :D :D

gunmetal grey has the ability to absorb light and sound so therefore is the fastest colour same as the time machine in back to the future :D :D :D :D :D :D :D :D :D

but The Delorean in Back to the future was Stainless steel, its closest colour being silver, not grey :tongue:

Thrust SSC is a British designed and built jet-propelled car developed by Richard Noble, Glynne Bowsher, Ron Ayers and Jeremy Bliss which holds the world land speed record, set on October 15, 1997, when it achieved a speed of 1,228 km/h (763 mph)

 

 

AND ITS BLACK ..... so enough said! :D

See I knew it... god I do love time machines...love that concept

 

 

How then do you explain the RED SHIFT which travels stait instead of following the Arc of space and time. In so being faster than light it self. Does it have a colour?

Or is it so fast as not to be able to attract one?

 

Does this mean that clear perspex cars would really be faster?

Red shift is something to do with items moving further away from you, eg expanding universe or red Zed's disappearing in the rear view mirror etc

Yeah Great, Silver cars can get to 88 miles an hour...... :rofl:

If you consider all the factors involved in achieving the speed of light outside of a pure and complete vaccum then it becomes obvious that the exact colour of the said vehicle is not the only consideration to be calculated and you should have taken into account if the car has HID's? because it would be much safer to go that fast if you can see where you are going properly.

:shock: Most people just think I'm barking and the red shift is *****cks

We must excuse AndyP for his imperfect notation of the formula...

 

..and to add that you are talking nonsense......

 

E=mc^2 is how it should be written

 

E=Energy

m=Mass ....... not M

c=Speed of Light

^2 = squared

Yeah, I couldn't suss out superscript for the "2", didn't think about the "^".

true but iff your moving faster than light then you will allways be ahead of the light beam projecting from your headlights which means your hid,s would become lights in your rear view mirror so you,d permantly be driving in darkness in which case how the hell could you see a black zed infront of you ;) you would just have to take my word that ime in front of you vinny because have you ever known me to lie :D :D

red is faster ....fact

 

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 snells 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 ocsillates 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 colors 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).

oy, be very careful with your choice of words :slap: :D

lol, wondered when someone would spot that one :D
