Sorry, don't understand the question. Wavelength is determined by freq.

Your question needs to be more specific:
What is the shape of the metal, is it a wire?
What are the boundary conditions around the wire?
Is this wire floating in freespace? Is there a ground plane nearby? How is the wire being driven by the source? Is the metal non-ferrous?
If the wavelength is 1 cm, then you are talking about 30GHz. At such a high frequency, very minor changes in your setup will change the impedance dramatically. At such a high frequency, engineers don't really talk about impedance, they talk about S parameters, because this is more easily measured, and more useful.

Assuming that the cross-sectional thickness of the conductor is much less than 1 cm, and that the composition is non-magnetic, the impedance should match free space.
