[Q]: passage: Miranda was a British television sitcom written by and starring comedian Miranda Hart. It originally aired on BBC Two from 9 November 2009 and later on BBC One. Developed from Hart's semi-autobiographical BBC Radio 2 comedy Miranda Hart's Joke Shop (2008), the situation comedy revolves around socially inept Miranda, who frequently finds herself in awkward situations. The show features actors Sarah Hadland, Tom Ellis, Patricia Hodge, Sally Phillips, James Holmes and Bo Poraj. It was filmed in front of live audiences at the BBC Television Centre and The London Studios.
question: is miranda filmed in front of a live audience?
[A]: Yes

[Q]: passage: 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).
question: is it possible to have a refractive index less than 1?
[A]:
Yes
