on your equations sheets, which equations are you including? i already have my basics, and i wondered if i should also include thick lense equations to complement the lense makers equation
Do you have the doppler shift equation?

Yep
check out google today! it goes right along with optics! i thought it was the greatest thing

I added the focal length equations for microscope, telescope, etc. I also just added the inverse sqaure law.
Besides those, I just have the basic equations you learn in a high school physics class.

Anything else I should include?
What constants are there?

I think the only constants are Planck's constant and the speed of light. Don't know of any others, or I can't think of them right now...

Units of measurement (lumens, watts, etc) are one of the possible topics for C division this year, so I would include some conversions.

You should probably start making your own templates...on the previous page, there were lists of programs different people used, like GSP, Asymptote, etc., etc. Just do the laser shoot as accurately as possible. Protractors help.
You’re not going to be at the Auburn Regionals, are you?

Seriously, can anyone help with the math?
You definitely DO NOT need to know how to do that math you posted, especially in B division. I could explain what each of those equations might be used for, if you'd like, but I can almost guarantee that no math beyond basic trigonometry and algebra is needed for this event.

Dr. Chalker, in the case that the laser beam gets split, what is the policy on which beam will be taken? I heard it was the brightest beam last year, but one competition I attended counted it as a miss because only one beam hit next to the target. can this question be resolved as soon as possible before regionals? Thanks

Unofficially, I'd think the brightest beam should be the one that matters. Does this happen that often in competition? I've never seen it in all the times I've run that event. I have seen an occasional diffraction pattern due to grazing the corner of the mirror, but that's a much different thing and easy to see where the center of the pattern is.

It happens surprisingly often. For my team between last year and this (counting several invitationals), we have split the laser a total of 4 times that I can remember. One being at states :roll: Thankfully they went with the brightest beam there and two of the other times. The only remaining one, they couldn't tell which was brighter and essentially made a right triangle between both endpoints of the laser and took the hypotenuse as the distance from the center point (the height was the distance to the center line and other length was the distance between endpoints of the laser).
