Recently in science class we learnt about rays and reasearched them this is my reasearch on Ultraviolet Rays.
Sources of Ultraviolet Rays
The sources of ultra violet rays are the sun, Flourescence/Flourophore and ionizing radiation. The sun has powerful rays that seep in through the ozone layer through patches of areas that are not covered. There is a test called woods lamp where you are in a dark room and they shine an ultraviolet light to anywhere you want. This shows you the light in your skin that can not be seen by the human eye.
What is this used for?
Ultra violet Rays are used for many interesting experiences. First Food preservation. The Food is passed through a machine that produces ultra violet Light. The light Kills all the micro organisms there fore making the food Germ free. Second they use the rays in Fly Trappers. Since flies are attracted to this light they go towards it and once they get to the light ZAP. The fly is killed. This is very useful in Kitchens and on camping trips.
DID YOU KNOW

_Did you know a black light or UV Light is a lamp that emits electromagnetic radiation.
