How does it work?
This hand held black light uses ultraviolet (UV) light that can cause many substances to glow or fluoresce. The torch's spectrum is confined to the low-energy, long-wave range of UV light, thus will not cause sunburn and will not harm eyes like sunlight. Still it's not a good idea to shine the torch directly into your own, or other people's eyes. Objects glow under black light, because they absorb the invisible UV radition and emit a light of a different wavelength that is visible to us as luminescence. The effect is awesome!
- The science of glow lies in the product's phosphors. A phosphor is a substance that radiates visible light after being energized.
- Ultraviolet light and the different wavelengths of light in the visible and invisible spectrum
