1 THz

Definition

1 THz (terahertz) refers to a frequency of one trillion hertz, which falls within the terahertz frequency range, typically defined as spanning from 0.1 THz to 10 THz. This frequency is significant because it lies between the microwave and infrared regions of the electromagnetic spectrum, allowing for unique properties and applications in imaging and communications. At 1 THz, electromagnetic waves can penetrate various materials, making it essential for non-destructive testing and security screening.
