Yes it can, and it does.
Radiation can travel through empty space. The radiation in question is electromagnetic waves.
what is a form of energy that travels as waves through the air and some solids and liquids call?

Electromagnetic waves or radiation
Electromagnetic waves do not require a medium, so they can transfer through a vacuum, or empty space.
Sure, electromagnetic waves are transverse waves.
Electromagnetic radiation, such as light, infra-red, UV, X rays.
Electromagnetic radiation... i.e., light. Electromagnetic Waves A+
Light energy, like from the sun.
Radiation is like light, it can travel through empty space. The "why" is a bit complex; basically, light, as well as similar radiations (including heat radiation) consists of electromagnetic waves. These can travel through empty space, since they are just waves in the electric and magnetic properties of space.
Radiation travels through empty space and substance.
