If the wavelength of light is 785 nm, what is the magnitude of the wave-vector? If the complex refractive index of the medium is ñ(2) = n₂ (2) — ik(2), then prove that the absorption coefficient of the medium is µ (2) = (²)×(1). Hint: Assume that your input wave is Ē(x, w, t) = e-ikx+wt; Further recall that I × |Ē|²
