Answer 1

Light is electromagnetic radiation. It requires no medium to travel through and can therefore propagate through both extremely sparse space, upper atmosphere and extremely dense plastics, water etc.

Sound however, requires sufficient medium to travel through. It is required to have the interaction of molecules of a medium, thus slowing it down.
