Lepton (1/13)



  1. For homework, I have to decide whether some objects or conditions block sunlight and their Ultraviolet rays completely, mostly, somewhat, rarely or not at all. I was given these following conditions: Water (not a bunch of water, like 1 cm deep or dripping leftover water Clothing (White Cotton Undershirt Sleeveless) Eye Glasses (The one people wear on their faces to see better) Window Glass Sun Glasses Sunscreen SPF 30 Copy Paper Ziploc Plastic Bag I'm guessing: Water - It shouldn't block any UV rays Clothing - It would probably block most UV rays Eye Glasses - Maybe some rays, like 30-40% Window Glass - It should block most UV rays but not all, like 80-90% SunGlasses - It should block all UV rays Sunscreen SPF 30 - It should block all UV rays Copy Paper - It should block most, like around 70%-80% Ziploc Plastic Bag - Maybe around 20-30% Can someone tell me whether my guesses are correct or incorrect and if they are incorrect, it explain why. I tried to base most of my guesses from how transparent they are, but I am not sure if that is completely related to sunlight. Edit: Or, I am looking at this incorrectly, maybe this is just a yes or no question on whether certain objects block UV rays or not, but I am not sure.
