The film discusses infrared spectroscopy, a powerful analytical tool that utilizes infrared radiation to analyze chemical compounds. It explains the nature of electromagnetic radiation and how ...

Electromagnetic spectrum and wavelength of terahertz waves ... Unlike X-rays, which are ionizing and can harm living tissue, THz radiation is non-ionizing due to its small photon energy and considered ...

The electromagnetic spectrum is a continuous range of wavelengths. The types of radiation that occur in different parts of the spectrum have different uses and dangers - depending on their ...

Often a phrase is used to help remember the order of the groups of the electromagnetic spectrum such as Roman Men Invented Very Unusual X-ray Guns. Each group contains a range of frequencies.

UV radiation is invisible to the eye and it is non-ionizing form of radiation in the 100 nm to 400 nm wavelength region of the electromagnetic spectrum. UV radiation is arbitrarily divided into UV-A ...
