A laser is shone through a diffraction grating and the diffradion pattern is created on a ruler as shown helow. As you can see, there are three dots on the ruler. Tl\"! center dot is the zeroth order and the dots on either side of the center dot are the rst order. Record the positions ofthe zeroth order dot {rm} and the rst order dots (ru for the left dot 8; rim [or the right dot) in the mhle below the picture crfthe diffraction pattern. Also record the uncertainty of your position rneasurernemts (0",) in the same table. Remember that this uncertainty is a good faith effort on your part identify by how much could your position measurements reasonably be off by
