In a dispersive medium...different wavelengths travel at different speeds.

Interesting. So if I have a red laser and a violet laser, and I fire both at sea level, what are their respective speeds? Are they much different than 186,000 mi/s?

Uneducated guess here, but I'd call 'em "High Speed", leave it at that, and go have a beer, but that's just me.
