**Official June 2013 SAT II Physics Thread**

<p>only thing… pitch and frequency are the same thing. It’s like saying what does velocity depend on and then answering with velocity…</p>

<p>resonance definitely depends on fundamental frequency, I just don’t know if it works the other way around</p>

<p>How about the question with the beam of light refracting through a convex lens, at an angle not perpendicular to the main line (or whatever it’s called)</p>

<p>^ that one is less than 30degrees</p>

<p>i put pi/2 for the circular speed of the man on the rotating plane.</p>

<p>^that is correct nig ga</p>

<p>i raped this chick… then i got aids, then i was like *** since when do 7 yr olds have aids, and then like *** im pretty sure i knew my little sister better than that. then i left because rotting bodies stink</p>

<p>I don’t really remember that question very well, but all I know is in class we learned frequency = pitch. So I’m pretty sure that’s the one I went with. Resonance might have something to do with frequency, but I think pitch and frequency are directly related.</p>

<p>^ya but the problem was talking about FUNDAMENTAL frequency doedeeede</p>

<p>Whatever frequency is frequency…haha I got pi/2 as well. Does any one remember any more of those Roman numeral questions? Some of those really annoyed the crap outta me.</p>

<p>all 3 waves demonstrate interference, all 3 waves transmit energy, only rope and light are transverse</p>

<p>Ok I’m pretty sure I got that too. Seems like I’m doing slightly better than I thought but still probably low score :frowning: any other questions?</p>

<p>for the capacitor and resistance the answer is q=cv but the tricky part is which v do you use since theres a v drop over the resistor so the v across the capacitor isn’t the same as across the battery</p>

<p>Guys I’m 100% sure it’s pitch. When a wave passes through a string lots of individual frequencies pass through, but only the fundamental frequency determines the pitch. The other frequencies contribute to the timbre of the sound.</p>

<p>Thanks @bojl95 for clearing it up. I skipped the capacitor ones haha.</p>

<p>uggh i did terribly on this sat --_____-
i’ll be lucky if i get over 700</p>

<p>Haha don’t worry @binatang I took 2 practice tests the day before and got below 700 on both (lots of stupid mistakes but I just didn’t understand some). And the real one was just as hard. So…</p>

<p>how does this test compare to physics B? AP</p>

<p>I’d say this test is definitely easier than the Physics B AP. The math on the SATII is a lot simpler than on the AP, despite the absence of calculators on both.</p>
