<p>I took it as more of a question about significant figures and measurement. We did a whole thing on it in Statistics.
I believe I put .5 +/- .2 or .1. Something like that</p>
<p>@xnakelx god bless ya, that’s what i’ve been trying to say</p>
<p>What did you get for the speakerphone question?</p>
<p>"On the other hand why doesn’t the collegeboard website offer past papers? "</p>

<p>No, Mr. Fancypants, the formula is sin(angle)=(m*w)/d, where d is the distance of the hole.</p>

<p>Are you so sure about the 800 now?</p>

<p>L is the distance from the hole to the wall and it does matter</p>
<p>no no! It wasn’t about Young’s Double Slit Experiment, it just said something like:</p>
<p>Light waves are incident on a screen with a hole on the other side and form a diffraction pattern.
The diffraction pattern will spread over a larger area if…</p>
<p>What score did you guys get?</p>
