WebBlack lights are a useful tool for rodent detection. Light is a form of electromagnetic energy that moves in measurable waves. The human eye is only capable of seeing a small segment of the light spectrum. This is called visible light. There are shorter and longer wavelengths that are not visible to our eyes. http://solar-center.stanford.edu/about/uvlight.html

WebThe colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end. White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. WebElectromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers . [1] In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz .
WebSince black light, for the most part, is not visible, it is very difficult to gauge its intensity. According to a study conducted by the International Radiation Protection Association, the …
WebThe term “black light” covers a wide range of wavelengths. from 310 to 450 nanometers. The common fluorescent black light has a peak at 370 nm.
