No matter what you do to either of them, light is always going to travel at least
several hundred times as fast as sound, and most generally about 800 thousand
times as fast as sound. Sound will never travel faster than light, in any situation.
No, slower.
it travels faster through air.
No. Nothing can travel faster than light.
The speed of light in any medium is given by its speed of light in vacuum divided by the refractive index of the medium and so light will travel faster in water than in glass since refractive index of glass is greater than that of water.
Luminescent glass is a glass containing or coated with a dye that absorbs sunlight. It emits light at longer wave lengths.
No
Both light and sound can indeed travel through glass. These are substances in which light and sound often travel through.
Travel faster than the speed of light. By definition, Superluminal is "Faster-than-light (FTL)"
No. Faster than light travel is impossible in any case.
It depends on how much light is shining on the glass. If there is a lot, then the water in the dark glass will evaporate faster because the temperature will be higher. If there is no light, then it does not matter.
Water.
Einstein stated that nothing can travel faster than light.
