Answer:
If electrons were made to vibrate at a frequency of a few million billion hertz (also known as terahertz frequency), the waves emitted would belong to the electromagnetic spectrum's terahertz range. These waves have wavelengths ranging from around 1 millimeter to 30 micrometers, making them shorter than radio waves but longer than infrared radiation. Terahertz waves have unique properties that make them useful in various applications such as medical imaging, security scanning, and wireless communications.
