Microwave

Microwaves are a type of electromagnetic radiation, like radio waves, visible light, and X-rays, but with longer wavelengths than infrared light. They travel at the speed of light and can penetrate certain materials, which is why they are effective for cooking food in microwave ovens. Microwaves cause water molecules in food to vibrate, producing heat that cooks the food. They also play a role in communication technologies, including satellite and mobile phone signals, because they can carry information over long distances without needing physical connections.
