11.4 Preliminary Assignment 1) A group of students perform the single slit diffraction laboratory. The distance from the single slit to the screen is (99.1+1) cm . They measure the position of the first order minima in the diffraction pattern to be: m = 1, y+1 = 0.0430 m and m = -1, y-1 = 0.0353 m. Determine the aperture of the slit for this experiment (with uncertainty). Compare your result with the accepted value of 0.16mm. 2) The same group of students changes the gain of the light sensor and measures the minima in the diffraction pattern. These minima are summarized in the table below. Plot the order number vs. position for these data. Calculate the slope of the line and determine the aperture width of the slit from this slope (with uncertainty). Compare your result with the accepted value of 0. 16mm. Order Number Position (m) 0.0018 0.0059 0.0099 0.0140 0.0178 0.0259 0.0298 UI A W N 0.0340 0.0379 0.0421
