This is sort of a blur to me since it's been quite some time, but I think you use: $E = hf = \frac{ hc }{ \lambda }$ where the greek symbol, lambda, represents wavelength.

I think Abb0t is right on the money again. I believe h is Planck's constant in this equation: http://en.wikipedia.org/wiki/Planck%27s_constant
