Optics B/C

On a different note, what have you guys found is the hardest thing to find stuff for? I still don't entirely understand what we're supposed to do with absorption spectra :b

As a test writer, I mostly base this off of astronomical phenomena (things like the Sun's absorption spectrum). I generally tend to include emission spectra in this category as well, because if you're willing to learn about absorption spectra, you might as well learn about emission spectra too

Along with the question posted above, I was wondering if there were any online simulations that anyone has used in order to practice the laser shoot, or if anyone is interested in creating one?

Practicing online is cheap, but you can buy a kit online for more than $50a t Ward's Science.

There is an online website that someone made (I think as a personal project) but it's not especially good for practice-I think it was meant mostly for theory of the general location to put mirrors. The WardSci one is quite pricey- $150ish per kit and $59 per laser, last time I checked.

Furthermore, the WardSci one comes with 5 mirrors, I'm pretty sure, so if you wanted to practice with the barrier mirror, you'd want to build one yourself, I guess. This could be done by just gluing a mirror (from like the local craft store) on the given barrier, which is what we did. It works pretty well ¯\_(ツ)_/¯

you can just make your own, it's really simple lol

By far the hardest part is finding mirrors that are small enough, but even that is not that hard (you can find some on Amazon)

In fact, we have a simple step-by-step guide to making one on the event page on soinc.org:

Most craft stores (Michael's, JoAnn) have mirrors that are the correct size. Something like a 5 pack for less than $5.

Hi guys, I probably should have asked this a while ago, but studying for other events has backlogged Optics for me. I'm basically done with the cheat sheet for the test, but I have no idea what they want for the optical absorption spectrum stuff like what sort of questions are they going to ask? Also, in terms of the LSS, my school ordered one to practice on, but it never arrived, so I have no practice/experience with it and will have to wing it, so what kind of stuff should I bring, and what should I plan for when I'm doing the LSS part? Once again, I would have practiced, but the kit never arrived. Thanks a lot!

Also, what do they want us to know on the test for Optical Absorption Spectra, and how many types of scattering do we need to know?

From what I've seen, it's just knowing the basic principles of what absorption spectra are, what they indicate, what THAT indicates, etc. I haven't seen anything too involved with them so far. As to the latter half of that question, I can't speak much to it, since the most I've seen this year on specific types of scattering was one reference to Rayleigh.

Thanks so much Avogadro, really appreciate your help!
