no
Straight line.
Light travels fastest through space which has no air. Space is a vacuum which is the fastest way for light to travel.
travels through a uniform medium
Light travels in straight lines through uniform materials.
Light travels faster than air. Its beam are straight so that it travels through holes.
A material through which light (or a certain color of light) won't pass through is said to be OPAQUE for light (or for that color of light). Most materials around us are opaque for visible light; only a few materials, such as air and other gases, water, and glass, are transparent, meaning they do let light through.
The name is "electromagnetic waves". They can travel through empty space, and - depending on the specific frequency - through certain materials. For example, light can travel through glass.
