it travels faster through air.
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.
Its because gold has a greater mass than glass
bounces of glass
Light's apparent speed is fastest definitely in a vacuum and slower in water or glass. Light in air behaves more like in a vacuum than in water or glass.
It is not. The speed of light in any material is inversely proportional to the refractive index of that material. The refractive index of glass depends on the glass and so the speed of light varies between 156 and 204 million metres per second. By contrast, the speed of light in vacuum is nearly 300 million metres per second.Even in pure water ice, light travels at nearly 229 million metres per second. So there is no evidence whatsoever to support the question's claim of "fastest through glass".
No, slower.
Light is an electromagnetic radiation that travel through air, vacuum, glass, plastics, ,,,
i dont know but the sound will stay more in glass

The denser the medium, the faster sound travels through it. Glass (silicon oxide) is fairly dense, and sound waves propagate through it faster than they do through air or water.

Yes, that is correct. (Slower than in a vacuum.)
No
