The energy of microwaves increases as their frequency increases. This means that higher-frequency microwaves carry more energy than lower-frequency ones. The relationship is direct: when frequency goes up, energy goes up too.
Microwaves, however, have much lower energy compared to ultraviolet or X-rays. Their energy is not strong enough to ionize atoms, which is why they are considered safe for most uses, like cooking or wireless communication. This energy-frequency link helps explain why microwaves can heat food (they transfer energy to water molecules) and why they are effective in certain communication systems without being harmful to human tissue.
