It's vacuum which means empty place. Because, of molecular structure. The molecules in glass (solid) place close together and the molecules in water (liquid) place together but with more space comparing to glass. But in vacuum there is lot of space between the molecules also comparing to hydrogen. So, the light can travel at the fastest speed in vacuum.

The speed of light is greater in vaccum as the light waves do not require a material medium to propagate. I think it is vaccum.

The speed of light at which light propagates through glass and air is less than c and because the value of c is less so the refractive index value is also decreases the refractive index is the ratio of c and the velocity of light in material thats why the speed of light is fastest in vacuum.

Speed of light in vacuum is 3*10^8 this is because there are less or no particles or gravity to slow it down.

The velocity of light in air is 3*10^8m/s.
The velocity of light in vacuum is 2.888*10^8 m/s.
The velocity of light in vacuum is 2.888*10^8 m/s.

@kriti.
Light velocity is 3*10^8 m/s.
Light velocity is 3*10^8 m/s.

Light waves are transverse waves they do not require material medium to travel. Hence they are called electromagnetic waves. Light waves travel in vacuum with the velocity 3*10^7 m/s.
