they use uv light because it works really well
To determine UV-absorption you need to use UV-light. And there's a defined wavelength for UV-light.
As UV only kill the Microorganism.Microbiological media contain the agar & for agar dissolve at 90 degree temperature that's why we cannot use UV to sterlize microbiological media
Ultraviolet light comes from the sun, and is what makes our skin darker, so we use UV light to tan ourselves in tanning salons.
on a mountain or a terrain are at night
it has specific wavelenth
Useful effects of UV are also there. Filters, locks etc use UV.
The ozone layer protects us from UV's. UV's are a part of sun's electromagnetic spectrum.
They are short chains of units which makes the gel harden under UV light
Glass is not suitable for use in UV spectroscopy because it absorbs UV light, leading to inaccurate measurements due to spectral interference. Quartz is preferred as it is transparent to UV light, allowing for accurate UV spectroscopic measurements without interference.
UV radiation cannot inactivate antibiotics. However, many industrial processes use UV radiation to sterilize antibiotic powders before they are pressed into tablets.
the adhesive active when exposed to UV, and the adhesive remain active afterward. Clear residue, work well for glass and optical window.
