It is the speed of neutrinos. Why they are faster than the speed of light? Ckeck results of recent LHC experiments.
The speed of light through air at sea level is roughly881 thousand times the speed of sound.
The speed of light is greatest in a Vacuum....300,000 meters/second. As the density of a transparent medium increases the speed of light decreases.Recent experiments with Plasma Gases have slowed down light beams to speeds of Feet/second!
Light does not change speed when it goes through glass.
Known as the Michelson and Morley experiment, this was an experiment to measure changes in the speed of light. Supposedly, as Earth travelled through the Ether, light would go faster in one direction than in the other (because of the relative velocities). The experiment didn't produce the expected result - the speed of light was found to be always the same. Today, this is an accepted fact - that the speed of light is the same for all observers - and is one of the bases for the Theory of Relativity.
You can do many, many experiments with the light. I'll just mention few categories:- Reflection of the light - Refraction of the light - Spectrum related experiments - Experiments that prove the wave nature of the light (interference) - Experiments that prove the particle nature of the light - Experiments that measure the speed of the light in space - if small scale, usually using interference etc... You may search on internet for specific experiments, by using the words of the categories mentioned upper, to narrow your search results.
Albert Michelson exemplified the new Navy's drive for professional development and leadership in naval sciences with his experiments on the speed of light.

Light is an electromagnetic wave, composed of fluctuating electric and magnetic fields, and these fields do not need the presence of any physical medium to support propagation. Before this was realised, people proposed that there must be some medium, given the name "the ether" to support the light. It was attempts to discover the speed of the earth through this "ether" which led ultimately to the theory of relativity and modern physics.
The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.

the speed of light, commonly denoted as "c", is constant no matter which medium it passes through.
