2. What are the different types of UV Light?
●UVA light (320-400 nm) is UV light with the longest wavelength, and the least harmful. It is also called black light.
●UVB light (290-320 nm) is UV light with wavelengths between 290-320 nm. About 5% of all UV-B light reaches our planet's surface.
●UVC light (100-290 nm) is extremely harmful and is almost completely absorbed by the ozone layer. It is created artificially to kill microorganisms (e.g. bacteria,  viruses, fungi, and mold).
