Optics+Lesson+1

So, you're thinking of outfitting your dorm room, and you want a "full-length mirror", but you don't want to waste your money. How much mirror do you need? With a partner, take a small mirror to a wall. Standing a meter or so from the wall, have your partner hold the mirror so the very top of your head is visible in the very top of the mirror. Anything higher than that is wasted, right? Then have them move the mirror down until you can see your feet in the very bottom of the mirror. Anything lower than that is wasted, right? So, how much mirror do you need? Does it matter how tall you are? Does it matter if you move closer or farther from the mirror? Check this out, and report back with your results!

Now open the Omnigraffle file called GeoOp1 in the Courses folder. Follow the directions there!

(Here is a pdf of the same document; though you cannot manipulate it in pdf format, a pencil and ruler could help!)
