You already gave the frequency range. Use the relationship between frequency, period, and speed of light given by the other guy. It is all just a little math and algebra. lagebra. Who said that I could spell.

I wont do your homework, but here are some hints,

frequency = speed of light / wave length for EM waves [i.e. lights], speed of light = 299792458 m / s , or 3E+8 m/s
