I was talking with a friend the other day who's an astrophysicist. (Tony- that means he's really learned. LOL).
Here's part of our IM conversation about the fastest color:
(01:27:41 PM)
KEVAN: Hey.
KEVAN: In the visible spectrum of light, which color travels fastest?
ASTRO: no color travels faster than another
ASTRO: it's all the same stuff, the only difference is the energy
ASTRO: in the visible spectrum, red light has the lowest energy, and violet light has the highest
ASTRO: the way that different colors of light have different energies, but still travel at the same speed, is that the energy is bound up in the light's frequency
ASTRO: red light has a low frequency compared to violet light
KEVAN: What about Black? ...and pure white?
ASTRO: black is the absence of light
ASTRO: so, effectively, black travels as fast as light
ASTRO: *pure* white light is more or less a collection ofphotons of various frequencies, those composing the full visible spectrum
KEVAN: So, it's the color's relative energy that is more/less than the other colors?
ASTRO: yeah
ASTRO: radio waves (photons very much less energetic than red light) and gamma rays (photons very much more energetic than violet light) all travel at the same speed, even though radio waves pass right through your body, and gamma rays will give you cancer
KEVAN: Ok.
KEVAN: I guess this settles the "fastest color" debates.
ASTRO: lol
Sorry for getting all geeky on everyone.
