far infrared in a sentence

Examples

1. The debris disk was discovered by measuring the amount of radiation emitted by the system in the far infrared portion of the spectrum.
2. On the other hand, some metals absorb only in the short-wave range and show a strong reflectivity in the medium and far infrared.
3. Some human proximity sensors use passive infrared sensing in the far infrared wavelength to detect both static and / or moving human bodies.
4. The QCL wavelength can be tailored across a wide range from the mid-infrared to the far infrared by changing the quantum well thickness.
5. The boundaries between far infrared, terahertz radiation, microwaves, and ultra-high-frequency radio waves are fairly arbitrary and are used variously between different fields of study.
