<p>water on a road is a very small medium transfer. it's very similar to polarized lens, since there is normally a large bounce back of light on the jagged road. However, when there is water, the light gets reflected away from our eyes and we see less.</p>
<p>What was the answer to two waves travelling toward each other? Is it travelling wave with 2A or standing wave with 2A?</p>
<p>Traveling I believe. How about the series of questions where they give you a displacement-time graph. What was the scenario that best modeled the motion? I put block sliding with constant frictional force. Also, what is the answer to the water/car question?</p>
<p>I think the one with displacement-time was A, where it said the block is sliding on a floor with negligible friction in one part and constant friction in another. The block moves at constant velocity for the first 0.3 sec, (no friction/force) then slows down constantly. (constant friction/deceleration)</p>
<p>Can someone explain to me exactly what kind of questions are one the test? Like can someone give an example of a question or something?</p>
<p>i agree with tritium on the block question. it was a standing wave though. look standing wave up on wikipedia. i think that's what the question was asking.</p>
<p>Yes tritium, you are right on the block question. And lightforce, I think you are also right on the wave question. Hmm I know I missed 5 already. Does anyone know if the curve will be drastically different from the one in the blue book? I'm hoping to still get an 800, but if they have a harsher curve, I will be disappointed.</p>
<p>well bluebook had a pretty easy curve in my opinion, and the test was also easier in my opinion, although they didn't provide explanations which really frustrated me haha. sparknotes only allows around 8 wrong to get an 800 so even on that track you should be fine with 5 wrong!</p>
<p>what book do you guys suggest to study with. </p>
<p>how long should you spend studying for the physics test if you want a score of 700+</p>
<p>depends how much you learned already</p>
<p>My son is taking Physics, Math II, and Chem in Nov. He's not too worried about Math or Chem, he's taken practice tests on those and gotten 800 and 780 with no prep. He's taking the physics practice this weekend. He has one year of high school physics, which he took last year as a junior. He's a little worried because even though his hs teacher was very good, he's in a small public high school and he thinks they probably did not cover as much material as other schools. For example, they did not cover thermodynamics until he was the only student left in the class, because he was the only junior and our seniors get out ten days early. He decided to take the physics though because he is hoping his strong math background will help and the curve is lower. What kind of prep book would you recommend for him with this background? Would the more difficult Barron's be appropriate or something more straightforward? He only needs the third test for Harvard, which is probably a reach for him anyway. (ACT 36, SAT I 800 M, 750 W, 740 CR, 2290)</p>
