Microwave technology involves the use of electromagnetic waves with frequencies ranging from 300 MHz to 300 GHz. These waves are commonly used for various applications, including cooking food in microwave ovens, transmitting data in cellular networks, and radar systems for weather forecasting and aviation. In microwave ovens, food is heated by exciting water molecules, causing them to vibrate and produce heat. This technology is also essential in telecommunications, where microwaves enable high-speed data transfer over long distances. Overall, microwave technology plays a crucial role in modern communication and everyday cooking.
