Thank you for the question... You can say radiation is the way energy travels, and energy travels in the form of waves. Light is an example of energy that moves by radiation. When you turn on a light in a dark room, the light bulb releases/emits light energy in all directions. The light waves spread through the air, filling the room and making everything visible. Radiation doesn’t need anything to travel through, it can move through empty space. This is why we can see sunlight from the Sun even though there’s no air between us and space. Hope this helps. Best wishes...
