From what I understand, higher frequency light travels a longer
path than lower frequency light due to the necessity of bouncing from
center to circumference and back more times per distance (shorter
wavelength = more waves per distance). If you could pull the 3-d
sine curves out into a straight line, the distance traversed per time
unit would be the same; however, taking the curved distance involved
in wave travel into account, higher frequencies will travel a bit
slower.
