FUV is a type of ultraviolet light with a wavelength of between 100 and 200 nm. It is invisible to the human eye but can be seen using special instruments such as UV telescopes. FUV radiation is harmful to living cells and can cause sunburn, skin cancer, and cataracts. However, it also has some beneficial uses such as sterilization and disinfection.
FUV radiation is produced by stars and other astronomical objects such as quasars and black holes. The Sun is the major source of FUV radiation in our solar system. When this radiation reaches the Earth’s atmosphere, much of it is scattered or absorbed before it reaches the ground. However, some FUV radiation does reach the surface of the Earth where it can be used for various purposes.
One common use for FUV radiation is sterilization and disinfection. This type of UV light can kill bacteria, viruses, and other microorganisms by damaging their DNA or RNA. This makes it an effective way to clean medical equipment or purify water supplies. FUV light is also used to treat psoriasis and other skin conditions.
Another use for FUV radiation is astronomy. This type of ultraviolet light can penetrate dust clouds that block visible light, making it possible to study young stars and galaxies that are hidden from view in optical telescopes. UV observations are also important for understanding how planets form around young stars.
