Move the computer pointer onto the graph so you see the hand icon. We need to expand the vertical scale to see the maximums more clearly. Your precision will be improved if you can use a larger value of n. Leave the crosshairs on top of the highest of the two maximums. Repeat for the right max with the same n value. If the number of your max was different from 5. (Recall that the central max is n-0.) Use the Smart Cursor crosshairs to measure the position of the max you chose and enter the value in the left x column of the table under the Data tab for the first 40 250 Run line. Under the central diffraction pattern, select a maximum that is far to the left of the central max as possible. The pattern should look like the example on the Intro page. Click and drag to the right until the right second diffraction max is near the right of the screen. The hand icon will be replaced by a parallel plate icon. Move the hand over a number on the horizontal scale. Click and drag to the left until the left second diffraction minimum is at the left of the screen. We need to expand the horizontal scale to see the maximums more clearly. We actually want 4 decimal places which means 4 significant figures when the positions is greater than 0.1 meters.
Then increase the number of significant figures to 4. Right click in the center of the crosshairs and select tool properties. Click on the Coordinate Tool (graph toolbar). Click on the black triangle by the Run Select icon (graph toolbar) and select the 40 250 Run. 40 250 Run OX - Lab 1.cap - PASCO Capstone File Edit Workbook Display Help B intro Single Slit Theory Double Slit Theory Setup A Setup B 1 Slit Procedure Slit Analysis 2 Slit Procedure 2 slit Analysis Data Graph Conclusions A A 6 A Smoothing 0 M L XL Rel intens 0.0929 m, 0.8 % 0.1120 m, 0.9 % 40 250 Run Relative Intensity (%) 0.0788 m, 0.2 % 0.1267 m, 0.2 % 0.070 0.075 0.080 0.085 0.090 0.095 0.110 0.115 0.120 0.125 0.130 0.135 0.100 0.105 Position (m) Double Slit Analysis: 1.
