Devices like UV sensors and photomultiplier tubes convert UV photons into electrical signals that can be quantified. Visible light occupies a narrow band in the middle, with colors ranging from red, which has the longest wavelength, to violet, which has the shortest.
Sun Emits Broad Ultraviolet Spectrum Across Different Wavelengths
This portion of the light spectrum is invisible to the human eye, yet it plays a crucial role in both natural phenomena and human technology. Position in the Electromagnetic Spectrum The electromagnetic spectrum arranges all types of radiation by wavelength and energy.
Ultraviolet light represents a specific band of electromagnetic radiation that sits just beyond the violet end of the visible spectrum. In forensics, UV light reveals latent fingerprints and bodily fluids that are invisible under normal lighting.
Sun Emits Broad Ultraviolet Spectrum Across UV Light Range
The shortest and most energetic category is UV-C, which covers wavelengths from 100 to 280 nanometers and is almost entirely absorbed by the Earth's atmosphere. However, the Earth's ozone layer acts as a protective shield, absorbing the most dangerous UV-C rays and a significant portion of UV-B.
