Do black lights emit uv rays
WebBlack lights emit ultraviolet radiation (UV light). UV is radiation with a wavelength just shorter than that of violet light, which is the shortest wavelength of light in the visible part of the electromagnetic spectrum. The electromagnetic spectrum is the range of radiation from benign radio waves to highly dangerous gamma radiation. WebBoth LEDs and Fluorescent blacklight fixtures emit light in the ultraviolet range. However, radiations are only on the UVA levels. UVA radiation is the safest of all three UV spectra (UVA, UVB, and UVC). However, they still …
