[Q]: Rescue from Gilligan's Island is a 1978 made-for-television comedy film that continues the adventures of the shipwrecked castaways from the 1964--67 sitcom Gilligan's Island, starring Bob Denver and Alan Hale, Jr., and featuring all the original cast except Tina Louise. The film first aired on NBC as a two-part special on October 14 and October 21, 1978. The film has the characters finally being rescued after 15 years on the island. The film was directed by Leslie H. Martinson.
[A]: do they ever get off of gilligan's island?


[Q]: 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♠2.6×10 for X-ray radiation at a photon energy of 6985480652946099999♠30 keV (0.04 nm wavelength).
[A]: can a refractive index be less than 1?
