CLOUD ABSORPTION OF ULTRAVIOLET LIGHT. Ben and Miho. The experiment was created to determine the effects that cloud cover has on UV radiation from the sun. While some sources supported a decrease in ultraviolet light, others found that UV light can rise from cloud cover. The experiment employed mainly ideas of ultraviolet light compared to other types of light. This involved light concepts, especially wavelength. Further, high energy, or fluorescent, solutions as well as the process for the creation of clouds were also employed throughout the tests. The results ended up reflecting that cloud cover blocks out a significant portion of UV light, rising as the cloud density rose. In fact, clouds, in the test, blocked out as much as 20% of the total UV light emanated. Therefore, the results conclude that, initially, UV light, and therefore, its dangers, would be diminished on a very cloudy day. This experiment contains much opportunity for further research. Further research could also take into account reflection off of the ground and attempt to create a more atmosphere-like setup.

These graphs show that fluorescent substance can "change" wavelength of light, and that clouds absorb UV rays.
