With this information I obtained: distance from laser to thewall was 126cm; when the light hit the wall we recorded 7dots x wasthe center and 2x2 was the distance of the dots on both sides ofthe center etc. (slit A width = .04mm with distance of the lightbeams on the wall respectively x=0mm 2x2=50mm 2x3=100mm 2x4=150mm)(slit B width =.04mm distance of the light beams on the wall x=0mm2x2=30mm 2x3=50mm 2x4=80mm) (slit c width=.08mm x=0mm 2x2=50mm2x3=100mm 2x4=150mm) (slit D width=.08mm x=0cm 2x2=40mm 2x3=50mm2x4=60mm)
1. Draw the interference pattern, labeling each of the maxima withtheir order number (calculation 1) and the angle (calculation 2)for each set of data.
2. Plot d*sin( ?), where d is the distance between the slits,versus the order number (calculations 1 and 2 below). Put the datafrom all your measurements on this graph.
Questions and Calculations
1. For each set of data, assign each bright spot an "order" bylabeling the central bright spot "zero" and counting outward inboth directions. Use only positive numbers.
2. Use your data for the location of each bright spot and thedistance from the slits to the wall to compute the angle betweenthe central maximum and other maxima, q. Compute sin(q) also.
3. From graph 2, find the wavelength of the laser light.
