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

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

 

 

What colour is a Bugatti Veyron, its grey, jaguar xj220, (silver which is a type of grey, and Mclaren F1. Grey. See grey cars are quickest.

 

Mine is grey but not fast. I look at it just sitting there doing naff all, and i feel grey. lol

Apparently if you could see an object approaching at light speed you would see it as red, then as it passed you and you see it going away from you, you will see it as blue, according to lightspeed theory anyway!!

 

So as i aproached another Z in my FAST WHITE one it would be blue and then as i overtook it it would turn red........weird!!!! :D

Right slight deviation.... Snells law:

 

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

 

the (theta1) and (theta2) is the deviation in degrees from the original course of the light (if i remember). Now when you shine a white source light and gradually move it from a perpendicular (right angle = 0deg) to a tangental (1-89) a one point, depending on the medium, it will eventually reflect rather than pass through the medium.

 

This is because as you increase the angle you shine it at the medium with (theta1) so the angle it refracts at (theta 2) has to increase. Eventually the angle is so great, because the light has slowed down it will exit back out of the medium on the same side aka a reflection.

 

This gives us the problem that:

 

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

 

so if the 'sin(theta1)' and 'sin(theta2)' are the same (angles of reflection are equal) then n1 and n2 are the same the refraction index hasn't changed, so the medium hasn't changed so it never touched the glass,

 

SO... why did it reflect?????? :nelson: :slap:

and then this come along and blew all of them away, regardless of colour :rofl:

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

 

Not if you got them from ChrisGreddy........ :slap: sorry chris (incase he comes back) :D

But it doesnt reflect, it would refract, and as white light is made up of all the colours of the spectrum, the different colours would refract at different angles.

black

Ok, my colour blue is the fastest . . . come on, you all know its been the perfect car

Yes I can see that after I read your sig :rofl:

And like I always keep saying Red is the fastest Z because Macca's is Red, and CJ ain't far behind, and Vinz!!! Think we should have a poll of Z colour and what BHP we've got and then add them all up to give a total! Think you'll find RED wins!!! Even the Z that's got the rear wheel drive land speed recold back in 1991 @ 263MPH was red!!!

of cours white cars are the fastest - thats why they spray the space shuttle and other rockets white. To make them go faster !!

BLACK,no doubt about it
