Re: Optics B/C

How many teams ended up using 5 mirrors at the laser shoot? Not sure. We used 4 mirrors, got 1 mm accuracy, and placed 3rd overall. Just wondering, did you notice the not-aligned-with-the-base mirrors? My partner and I made our templates assuming that they were, and we didn't notice that the mirror...

Re: Duration

Just to get a sense of the competition, what was the breakdown of times at Nationals last year? What place do you expect a helicopter with a 2:10 (or so) time would get? If I recall correctly, my teammates had a shade over 2 minutes as a flight time and placed 15th. This was in a dome with a high c...

Re: Remote Sensing C

Has anyone see any digital image processing questions on the tests? Actually, on my States test (I'm partners with Haverstall), there was a question: Which of the following processes is used to reduce noise in an image? A. Eastman B. Mie C. Fourier D. Hotelling Of course, we had no idea what it was...

Re: Optics B/C

Does anyone have any good resources for the operating principles of optical equipment and learning pretty much anything for the Physical Optics part of the test? In addition to foveverphysics' link, I found http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html very helpful. You might need to dig a...

Re: Optics B/C

:D Awesome! I'm in 9th grade & this is my 1st year in Sci Oly. I haven't learned that much about optics (pretty much all I know is the angle of incidence equals the angle of refraction). :lol: Anway, that is really great news for me. 8-) Good luck! Optics is a ton of fun, and it's amazing to see ho...

Re: Optics B/C

The rules say something to the lines of "all reference materials must be kept in a three ring binder." Does that mean we can bring whatever reference materials we want? :) Yep, as long as they are 3-hole punched. While this means you can bring as many notes as you want, it's usually to your advanta...

Re: Optics B/C

Hey guys, I have a question I had trouble with on my State Test; Image is attached. Basically, with green and magenta lasers shining on a red bottle on a white table, what colors appear on the bottle when the laser hits the bottle, and the shadows behind; fill in the blank spots. Thanks! http://img4...
