SUMMARY
The refractive index of polycrystalline silver is characterized by n=0.135 and k=3.999 at a wavelength of 633nm. The term "nk" refers to the complex refractive index, which indicates both the phase velocity of light in the material and the absorption characteristics. The wavelength within the silver is calculated using the formula 633/nm, not 633/0.135 nm. Understanding the refractive angle in metals requires knowledge of the skin depth, beyond which incident radiation does not penetrate, as discussed in Born & Wolf's "Principles of Optics."
