microwave
含义: Electromagnetic radiation with wavelengths between infrared and radio waves, used in communications, radar, and the familiar kitchen appliance that heats food by causing water molecules to vibrate.
Microwave frequencies range roughly from 300 megahertz to 300 gigahertz. Beyond cooking, they are essential to mobile phone networks, satellite communications, Wi-Fi, and radio astronomy. The cosmic microwave background — residual radiation from the Big Bang — is a cornerstone of modern cosmology. In everyday British English, 'microwave' functions as noun, verb, and adjective.
