...That is another question for you photo egg heads, do some colors
travel faster than others?
I understand that whole frequency thing but if each one is
vibrating at different speeds do all colors get to the eye
at the same time?

In vacuum, all colours travel at the same speed. Any kind of matter
slows them down to some extent, depending on what kind of matter it
is (that´s why glass lenses work, but that´s a long story that Andy
would tell much better...). And it slows different colours to
varying extent (that´s why a prism gives a spectrum, and that´s why
our lenses are blessed with chromatic aberrations).
So, in theory we should be able to use VERY fast shutters instead of
coloured filters...... ;-)
