Thanks for the quick response. I hope the upcoming regional contests will follow the rules.

There should really be a thickness restriction on the mirrors because at Tiger, the thickness of the blocks was ridiculously thick and it was quite a pain...the blocks were thicker than the mirror was wide...

You can put paper under the mirrors, I believe, so you can premake a few templates for almost all possible circumstances.

I'm always worrying about that too. Some of my templates have the mirrors go right up against a corner of the lss, so if its too thick it won't line up correctly. there should really be some regulations on that

i second that notion. at reigionals the blocks were really thick, and it was hard to get the right angle measurements

Last year at state, they gave us this mirror that was glued to a wood block that was about 2"thick, 3" tall, and like 16" long.
Thing like that make me stop to say "wtf?" (as in "what the fruit?").

Winning angle was like 52 degrees or something. It made me mad. We could have won. However, for all my fast thinking, I did not see the solution that was right in front of my eyes that entire time.

Well, to measure the angle, you could just line up the front of the mirror with the mirror line on your template, which would be the most accurate way.
Also, there is a real accurate setup using 4 mirrors at -45 degrees and 45 degrees, that could be used no matter how the obstacles are set up. This could be used a sort of a backup, since it only uses 4 mirrors, or you can change the last mirror, and add in the 5th mirror.

Hey, just a quick question regarding what to study for State. What exactly is Young's experiment and how does it relate to interposition/superposition of waves? Is it related to path difference?
Thanks!

That's exactly what I did, and I got 39.5/40 points. Just out of curiosity, what programs do you guys make your templates with? Or do you draw them?
