THE EFFECT OF SUNGLASSES AND ALBEDO ON UV LIGHT INTENSITY. Ben Causey, Emma J-R, Alex Smith. This lab tested the effectiveness of UV protective sunglasses and whether or not a snow on the ground increases sunburn. This was simulated through measuring the brightness of UV rays reaction with fluorescent fluid. In the first test, the UV light traveled through only a sunglass lens to see how much light was cutoff. The second part of the lab simulated the albedo of a snow bowl with a bowl of mirrors. The results showed that one pair of sunglasses eliminated 83% of the initial UV light and the second pair eliminated 75% of the light. Therefore UV protective glasses are somewhat, but not fully protective as the label indicates. As for the albedo’s effect, it increased UV light intensity by 61%.
