Yes! Thank you for the explanation, especially the last bit. We covered the Law of Malus in my class, but didn't refer to it by that title. I think the thing I was really missing was the fact that the average of cos(sq) is 0.5, which makes complete sense if I graph it and think about it...
This is more of a conceptual question:
Where does the equation for the intensity of polarized light come from?
I know the standard form is:
I=(1/2)(I_0)
after the EM wave passes through the first polarizer. Why is that? Why is the intensity exactly half?
The polarizer ensures...
I hate to say it, but I'm pretty sure the current teacher is the latter. My AP Chem teacher from last year used to teach the AP Bio class. He decided he had too many courses and dropped Bio for this year.
Good suggestion. I'll see if his teaching style is a little more effective in making...
Well... This woman has never taught an AP class before. She's basically splitting the year with another teacher who has never taught the course either. They're both teaching what they "like," so a lot of the course is out of order. We're skipping a lot of things (about ten chapters) that I hope...
I spend about two hours a day, no joke. At first it was only about an hour, but that put me in the C range. Now I'm at a low B, with all the studying. I suppose if I pitched in something like four hours, I might muster an A. Do people really spend that much time studying per day?
No one in my AP Bio class has an A. Not a single person. The highest we've gotten yet is an 86%, and that's from the girl who studies three hours every day. Is this normal? We're nearing the end of the semester, and yet most of the class has Cs and Ds. It's the teacher's first year teaching AP...
