Light is an example of an electromagnetic wave. Electromagnetic waves can travel through the vacuum of interstellar space. They do not depend on an external medium-unlike a mechanical wave such as a sound wave which must travel through air, water, or some solid medium. Here's a project where you can quantify how much difference color makes for absorbing heat.
