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.
Light travels slower through denser media, so it travels faster through water than through a diamond.
Light travels fastest through vacuum.
it travels faster through air.
Light travels fastest through space which has no air. Space is a vacuum which is the fastest way for light to travel.

Light travels fastest through vacuum.
light travels faster in vacuum.
it travels faster through air.
Light travels fastest through space which has no air. Space is a vacuum which is the fastest way for light to travel.
Light travels much faster than sound, through wood.
Red light.
Light travels faster than air. Its beam are straight so that it travels through holes.
Light travels faster than sound ... about 875,000 times faster. Nothing travels faster than light.
lightning travels faster. Light is faster than sound.
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
