input: Northern Mariana Islands

The Northern Mariana Islands, officially the Commonwealth of the Northern Mariana Islands (CNMI; Chamorro: Sankattan Siha Na Islas Marianas; Refaluwasch or Carolinian: Commonwealth Teel Faluw kka Efang llol Marianas), is an insular area and commonwealth of the United States consisting of 15 islands in the northwestern Pacific Ocean. The CNMI includes all islands in the Mariana Archipelago except Guam which is the southernmost island of the chain and a separate U.S. territory. Along with Guam, it is the westernmost point (in terms of jurisdiction) and territory of the United States.

input: Refractive index

According to the theory of relativity, no information can travel faster than the speed of light in vacuum, but this does not mean that the refractive index cannot be lower than 1. The refractive index measures the phase velocity of light, which does not carry information. The phase velocity is the speed at which the crests of the wave move and can be faster than the speed of light in vacuum, and thereby give a refractive index below 1. This can occur close to resonance frequencies, for absorbing media, in plasmas, and for X-rays. In the X-ray regime the refractive indices are lower than but very close to 1 (exceptions close to some resonance frequencies). As an example, water has a refractive index of 6999999999740000000♠️0.99999974 = 1 6993260000000000000♠️2.610 for X-ray radiation at a photon energy of 6985480652946099999♠️30 keV (0.04 nm wavelength).
