Correct - The UV comes into the car - gets absorbed and converted to infrared (heat) - then the glass holds the infrared in making it super hot. If glass couldn't pass UV plants would die in greenhouses |

Another thing you may want to try if you park your car in the sun, is a sun shade. It is a bit of a nuisance, but it also keeps the car cooler.

that's odd, I remember vaguely doing an expereiment in a micro lab where we held plastic petri dishes of bacteria under a UV light with and without the plastic covers on the dishes. The take home points of the experiment were that the bugs were sensitive to UV and that UV did not penetrate too deeply, i.e., through the cover of the dish. As for the idea that if glass blocked UV plants would die in greenhouses seems counterintuitive. If UV light is known to cause eventual DNA mutations... why would plants miss it? I believe plants absorb all visible light other than green -which is reflected back for us to see pretty leaves with. Most likely some UV penetrates through glass and plastic and that is why people put additional protection on glasses and windshields.

There are more sites I could quote. But while a large portion of UVb rays are blocked by glass.. no UVa rays are. And they make up a bulk of the UV rays hitting your car.

billabong,
The following was a little insulting, I didn't miss it there was just a real cute girl in my class that I had my eye on Actually, because of reasons like that I missed most of the middle school classes too. "Plants don't need UV? You must have missed the lecture on photosynthesis in 5th grade" I posted after I had searched on line to double check what I had intuitively thought. I read that: Chlorophyll a & b absorb light in the red and blue regions of the visible spectrum... if your 5th grade class was furhter along than mine, perhaps you'd be willing to share... CDT
