Find the wavelength

  1. Nov 20, 2007 #1
    I'm trying to determine the wavelength of a particular situation. I'm given the refractive index of the metal and the value of the plasma frequency, and I'm asked to find the wavelength (or frequency) of a particular ray in this situation. Unfortunately, I'm not terribly able to even begin answering this question. Help?

    Wavelength times frequency gives you the wave propagation velocity. You have frequency, is there any way to determine the wave propagation velocity from the given information?
