Hi all,
can the angular frequency of a electric waves be used to determine the wavelength using the following;
ω=2πf
rearranging for the frequency, and using the following;

E=hf=(hc/λ)

or can this formula no be used as it is dealing with photons?

yep, that's fine. all you're really doing is using the two equations: $\omega = 2 \pi f$ and $c=\lambda f$.
