Which color really is faster?

[psnbye]

I just want to know why the blue one is the fastest one? I have a red one and it is pretty stinking fast. My uncle has the blue one and it is fast, but faster just 'cause it's blue? Blue does look good, but my red is bootiful too!

You sure you want to stir this pot ??

RED. Period

 

[hardway]

Black, obviously!

The colors of the visible light spectrum[2]
color wavelength interval frequency interval
red ~ 700–630 nm ~ 430–480 THz
orange~ 630–590 nm ~ 480–510 THz
yellow~ 590–560 nm ~ 510–540 THz
green ~ 560–490 nm ~ 540–610 THz
blue ~ 490–450 nm ~ 610–670 THz
violet ~ 450–400 nm


Color /nm /1014 Hz /104 cm−1 /eV /kJ mol−1
Infrared >1000 <3.00 <1.00 <1.24 <120
Red 700 4.28 1.43 1.77 171
Orange 620 4.84 1.61 2.00 193
Yellow 580 5.17 1.72 2.14 206
Green 530 5.66 1.89 2.34 226
Blue 470 6.38 2.13 2.64 254
Violet 420 7.14 2.38 2.95 285
Near ultraviolet 300 10.0 3.33 4.15 400
Far ultraviolet <200 >15.0 >5.00 >6.20 >598

As you can see from the charts I lifted from Wikipedia blue has a higher frequency and more energy than red. Red has a longer wavelength. This means blue is faster but red bikes are longer.

hahaha.... why must we argue over the simple answers...

















answer: blue

Silver isn't listed Guess that means mine is the slowest of all of them :thumbdown:

 

[Sawblade]

Silver includes ALL the colors in the spectrum, so it's ovbiously the fastest.

What happens when you paint a blue one red? Besides getting a purple bike, that is....

Actually, the way I see it, if blue light is higher energy, the paint absorbing it would get hotter than red paint. This excess heat would make the fairing on the blue bike bigger because of thermal expansion, leading to more drag and a slower bike.

I actually bought red and blue touch up paint a while back and took UV-VIS spectra for each paint to determine total energy absorbed by each paint, but stopped because the results would be inconclusive anyway without knowledge of wavelength intensity distribution of the sun. If the blue light waves are higher in energy but there are fewer coming from the sun (likely, as due to Rayleigh scattering we lose a lot of blue light), the effect could be canceled.

One quick way to answer this question would be empirically; just measure the surface temperature of each bike (side by side of course, sitting in the sun long enough to fully equilibrate). I have a surface thermocouple probe that I can bring with me next time I meet up with someone who has a blue bike.

Okay, was that too geeky?

 

[Tim77]

Raven (black) is actually the fastest one... IMHO

 

[Stumbles06]

Silver includes ALL the colors in the spectrum, so it's ovbiously the fastest.

I'm with Sawblade on this one... Silver... No doubts :Flip:

 

[paulinus]

Okay, was that too geeky?

Loved the comment Definitely not too geeky for me. I like where this thread is headed. LOL

 

[#27]

I have convincing PROOF that BLUE is faster.

I started speaking with a Gentleman in a Yamaha dealership today, he was on a RED CBR 1000. I mentioned I was headed up to a Triumph/Yamaha Dealership right after I left here, about 25-30 miles away. Surely a significant distance to correctly gauge speed.....
We spoke again briefly in the parking lot, as we BOARDED our bikes. Mine BLUE, his RED
2 hours later, after a stop for some Lunch....I arrived at the Triumph/Yamaha Dealer.
By coincidence, the same gentleman arrived, on his RED CBR, nearly 20 whole minutes after me! He too stopped for LUNCH! I can only deduce, that BLUE.....must be faster!:Flip:

 

[Humperdinkel]

I'm with Sawblade on this one... Silver... No doubts :Flip:

Im with stumbles and Sawblade , nothing is faster than silver

 

[sideshow_downs]

Red, Blue and silver may be fast but the Stealth Raven is better because will get past the cops while all the other bright flashy colors will be on the side of the road :Flip:

Good enough for me :thumbup:

 

[SovietRobot]

Noobs, red is fasterest than all the fastness int he fastiverse.

This topic was debated extensively in 2007 lol. There was a member who posted up a really good explanation about how light travels and is seen by the optic of the eye, very similar to Chemakers post. Based on the speed that colours travel he concluded that the........................... Dam I can't remember lol.

Wrightme contributed extensively on the original thread.

There are two things I do know for fact:
1) The more discerning rider will ride the silver and black one.
2) All current models will be faster than the 2010 models.

Hi Chem,
Not to geeky at all. I would like to modify your experiment ever so slightly and make it more biker science.
Keep all of your principles, but instead of measuring the bike surface temperature.

We get Wolfman to bring a couple of glamor models (they have to be identical twins, to negate any calibration errors). Stick the bikes out in the sun and get the girls to sit on the bikes. We then take surface area measurements from carefully pre-selected body areas.

Your thoughts please?

i dont really have anything to add. But i do like where you are going with this. Oh and we need pics when this experemnt is performed :thumbup:
