I am having trouble with my calculations. My average is double what it is supposed to be. It is possible I'm not understanding how they want the conversions. Here is the lab and data

art B - Quantitative Measurements Single-Slit Diffraction: 1. Change the component to the single-stit stand and re-plug the laser. 2. The distance between the laser and the stand should be 10.0 cm. - Meastare to verify! 3. The distance between the stand and the screen should be 105.0 cm. (a) Measture to verify! 4. Your L=105.0 cm; record it into your lab notebook. 5. Select the a=0.16 mn slit: a. Sketch the pattern on the paper; label it as "Part B /a=0.16 mm " Pictures are not an acceptable alternative! b. You sketch it by outlinaing the maxima. c. Indicate the central maxima. 6. Unplug the Iaser - do not disassemble the setupt 7. With the calipers: a. Measure the width of the central mareimu; record it into your lab notebook. b. Take half the width as the center of the central mexime indicate it by drawing a pertical line through it. That redical line is the zero or origin of your coordinate systern. Positions and orders to its lef are taken as segutine values. Positions and orders to its right are taken as pectioe values. c. Find the midpainis of the gaps between the manna; indicate the midpoints by drawing dots at their locaticns. (3.) These dots represent the positiond of the minima- d. Label the mandimi order at m=−1,m= 2, m=−3, che going fiftuarid frum the creigh
c. Find the midpoints of the gaps between the maxima; indicate the midpoints by drawing dots at their locations. These dots represent the positions of the minima. d. Label the minima orders as: m=−1,m=−2,m=−3, etc, going leftward from the origin m=1,m=2,m=3, etc, going rightward from the origin e. For each minima, measure its position (x) relative to the origin. m is the order of the minima. If m<0, its position, x, is negative. If m>0, its position, x, is positioe. Write the positions under the minima at the paper. 9. Create a table for your data in your lab notebook: a. 1' column is the order (m) from most negative to most positive b. 2m column is the position (x) for the order (m) c. 3"t column is the width (a) for the order ( m ) 10. For each minima order (m) and position (x), and assuming A=650 mm, use the following to calculate the width (a) : a=mλxL a. Equation 8-10 comes from Equation 8−4 solved for a. - Verify it in your lab notebook. b. Be careful with signs! Your m, x pairs are either both positite or both nexative, therefore, a is always pasititel c. Be careful with units! Keep your A. L. anid x valucs in mm. 11. Average your widths, take the percent difference with your meaured width.
