The speed of light is constant in a given medium.

Light can travel through undistorted
Light waves travel fastest through vacuum, at nearly 30 million meters per second. Light travels more slowly through other substances such as air and water, and can be absorbed.
electro-magnetic radiations Light.
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
slow down.
Light travels much faster than sound, through wood.
Light travels fastest through vacuum.
Air.
it travels faster through air.

Light generally doesn't travel faster through solids than through gases. Sound does, but not light.
It doesn't travel faster through a vacuum. In our Universe there is no such thing as empty space.
Light travels slower through denser media, so it travels faster through water than through a diamond.
Light travels fastest through space which has no air. Space is a vacuum which is the fastest way for light to travel.
