Optics B/C

I looked it over again, I think it was talking about chromatic aberrations, which would make a lot more sense. Sorry for the confusion, it was pretty late at night when I read this. ><

I believe that chromatic aberration is like when the colors don't focus at the same point because of the different indexes of refraction?
That would make sense cause you can use multiple lenses to bring the different colors into focus at a single point.

Yes, that is what it means. For some reason I copied it down as spherical abberation...

So on the rules sheet, it says we have to know "structure and function of parts of the human eye"

Does anyone who has competed in the event before know exactly which parts of the eye we should cover? Or do we need to know all of them?

Thanks.

All the practice tests I've seen have pretty basic eye diagrams like this (which even might be too much):

Alright. I'm studying with the 2011 Nationals Division C Test
http://scioly.org/wiki/Test_Exchange#Optics

I think it should have most of what should be covered.

Good idea, but you never know with these things, always good to study more than what's required to get a deeper understanding of things.

Since we are starting to get these types of questions from lots of people, I'll provide a 'standard' reply:

There is really no way to answer questions like these. There are hundreds of tournaments around the country, all run by different event supervisors. There isn't some secret 'event supervisor manual' that tells them how to make the tests... they see the same rules as you do. Thus it's totally dependent on the specific supervisor you have as to what the test will be like.

Alright thanks!

Also, for the laser shoot, by 4 minutes set-up time, does it mean the time after calculations to set it up or the total time including the calculations? I'm assuming that its the latter.
Since it's my first time doing this event, I'm thinking that the calculation time will not take too long, since it's basically just using the reflection angles to calculate. If you have done this before, does the time limit act as a major or minor constraint? Thanks!

The set-up time includes the calculations.
Last year, you were given points for doing the laser shoot in as little time as possible, as well as for accuracy. So, most people who scored well probably did it in under 10 seconds
This year, the time component is replaced with the number of mirrors used, so I'd imagine that more people will use the full 4 minutes.

My partner and I mostly took notes from the section on eyes in a few Biology textbooks. (this is usually under the anatomy section.)
You're allowed a binder for this event, so as long as you keep everything organized, there's no such thing as to many notes!
