WebAug 1, 2024 · Radio waves are a type of electromagnetic radiation: an umbrella term that includes visible light, infrared, and X-rays, all of which are a form of energy. Energy excites molecules, and excited molecules are hotter. But excited molecules aren't just hotter — they're also in a state of higher entropy.
