No, slower.
Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.

Yes.
It travels fastest in a vacuum.
Light travels fastest in a vacuum because there are no particles to slow it down. It slows down in air, even more in water, and even more in glass due to interactions with particles in those mediums.
The index of refraction for glass is calculated by taking the speed of light in a vacuum and dividing it by the speed of light in glass. Since light travels 1.5 times faster in a vacuum, the index of refraction for glass would be 1 divided by 1.5, which equals 0.67.
Light is an electromagnetic radiation that travel through air, vacuum, glass, plastics, ,,,
Nothing can travel faster than light in a vacuum.
According to the theory of relativity, nothing can travel faster than the speed of light in a vacuum.
No.
Light travels faster through space than through a window. In a vacuum, such as space, light moves at its maximum speed of approximately 299,792 kilometers per second (186,282 miles per second). When light passes through a window, it slows down due to interactions with the glass, which has a higher refractive index than a vacuum. This causes the light to travel more slowly in the glass compared to its speed in space.
