Ultraviolet light in sunlight can cause the skin to tan or burn. Fluorescent substances are used in energy-efficient lamps - they absorb ultraviolet light produced inside the lamp, and re-emit the ...

UV radiation differs on the basis of wavelengths. UVA has a medium to longer wavelength and can therefore reach deeper into the skin. UVB has a shorter wavelength, which is why it is used to treat ...

The realization of compact and reliable diode-pumped solid-state lasers that emit UV light is now opening the door to new industrial applications. Neil Savage describes the uses of the technology ...

Therefore manual cleaning is needed first. UV light has been used for decades in water and air purification, and used in laboratories. But combining them with autonomous robots is a recent ...

Ultraviolet (UV) lamps emit electromagnetic radiation with a wavelength between 10 nanometers (nm) and 400 nm, which is below the visible light spectrum. UV lamps have industrial uses in sterilization ...

Most people know that one of the best ways to treat mold on a household item like a blanket or piece of upholstered furniture ...

We are faced with a global epidemic of myopia (short-sightedness) because we are deprived of deep violet light (360-400 nm).
