## The above answer is correct for certain wavelength, for metal, especially for longer wavelength, the refractinve index is complex number. But when wavelength become shorter, to X ray wavelength or even shorter, metal bacome transparent, and might finally have a real refractinve index.

Refractive Index of Al, Aluminium Aluminium or aluminum is a silvery white member of the boron group of chemical elements. It has the symbol Al and its atomic number is 13. For a typical sample of Al the refractive index and extinction coefficient at 632.8 nm are 1.37289 and 7.617691. 32 Refractive Index of Dense Materials. Review: See Table 32–1. For $\omega<\omega_p$ the index of a metal has an imaginary part, and waves are attenuated; but for $\omega\gg\omega_p$ the index is real, and the metal becomes transparent. You know, of course, that metals are reasonably transparent to x-rays. Notes on the Refractive Index of particular elements: Carbon: Value given for diamond form.

### A method for measuring the refractive index of metal bulks in the terahertz region with terahertz time domain vertical reflection spectroscopy is proposed.

When a light wave of the form E=E 0 e iω hits the surface of a metal, the refractive index if given(considering restoring force of metal atoms and damping equal to 0), by n 2 =1-p 2 /ω 2 where Optical constants of transition metals: Ti, V, Cr, Mn, Fe, Co, Ni, and Pd, Phys. Rev. B 9, 5056-5070 (1974) Data [ CSV - comma separated ] [ TXT - tab separated ] [ Full database record ] The complex refractive index of metal has signiﬁcant eﬀects on plasmon waveguide performance. We measured the complex refractive index of gold in the terahertz frequency range using terahertz time-domain spectroscopy (THz-TDS).

## If the response is sufficiently strong and out-of-phase, the result is a negative value of permittivity and imaginary index of refraction, as observed in metals or

Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers. There are also weaker dependencies on temperature , pressure / stress , etc., as well on precise material compositions (presence of dopants , etc.); for many materials and typical conditions, however, these variations are at the percent level or less.

It is defined as where c is the speed of light in vacuum and v is the phase velocity of light in the medium.
