got it, thanks!JustDroobles wrote:Yes.Zest wrote:Is the formula to find frequency wavespeed/wavelength or 1/cycle duration, or both?
For all waves, where v is velocity (or as you said, wavespeed), f is frequency, λ is wavelength, and T is period (or as you said "cycle duration"):
v=fλ
f=1/T

So... does anyone know?

Please note in particular #2: "Unless otherwise stated, it is generally understood that if notes, resources, calculators, actions, etc., are not excluded, then they are permitted unless they violate the spirit of the problem."
That rule guides a lot of the responses we generate to questions submitted on soinc.org, and is a big part of why templates are allowed this year.
if this is true, then what type of template is being reffered to? I've just been using rulers and protracters to complete the laser shoot.

Re: Optics B/C
I do (since I wrote the test;), but I have a general policy of not providing answer keys to my tests. I think the learning experience is better if you have to work through the questions and feel confident in the answers, rather then just skimming them over. That said, I will answer questions about specific items on the test if there are ambiguities or confusion about them.Zest wrote:does anyone have the answer key for the texas 2011 regionals test (from the test exchange)?

Re: Optics B/C
Actually it's a combined B & C division test. The regional was pretty small and I only wrote the test (wasn't there to proctor it). Thus I felt it would be better for everyone to have only 1 test for both divisions. The scores in the B division were a bit lower than the C division, which is to be expected.smartkid222 wrote:that's a division B test right?

Re: Optics B/C
That is not a correct interpretation. The Optics rules explicitly state what MAY be brought. We've made a decision that a template that fits in the binder is a reference material and thus falls under the reference material clause. The spirit of the rule for Optics is obviously that anything not listed may NOT be brought.Zest wrote:So... does anyone know?
