EMC (electromagnetic compatibility) is defined in the EMC Directive 2004/108/EC as the ability of a device to operate satisfactorily in an electromagnetic environment without itself causing electromagnetic disturbance that would be unacceptable to other devices in that environment. In EMC, a distinction is made between electromagnetic emissions (EME) and electromagnetic immunity (EMS). Electromagnetic interference emission […]
Light that is visible to humans (visual) is electromagnetic radiation with wavelengths between around 380 and 760 nm. Below 400 nm, we speak of ultraviolet radiation (UV), which is extremely hard UV radiation down to 10 nm. The UV ranges of radiation, which also include sunlight, are referred to as UV-B from 280 – 315 […]
