Enter your measurements manually. 0.0105 19836- 364 0. 0135 255 68. 182 0.0025 0.0050 0 0075 0.0100 0.0125 X 7. The remaining columns are calculated columns. Select "New Calculated Column" from the Data menu and enter an equation to calculate xn. Repeat SPH4UR Lab: Young's Double Slit Experiment for the fourth and fifth column. Purpose: To determine the wavelength of the green laser. 8 . Create a graph of an versus - 2and determine the slope. Apparatus: Central Maximum Analysis: Laser 54 3 2 1 1 2 3 4 5 K- A 1. Based on the slope of the graph, the wavelength of the laser is 5.28 107 2x , Slit plate 2x2 Screen 2x3 2. Determine the uncertainty of your calculation. Procedure: 1. Position the slit plate and line up the laser so that it passes through 3. Calculate the percent difference between your experimental value for the 2. Tape a sheet of chart paper to the white board. Mark and label the wavelength of the laser and the known value locations of antinodal lines 0 to 5 in both directions on the paper. Turn off the laser when you are done. Remove the paper from the board. 3. Mark the location of the nodal lines 1 to 5 in both directions. Measure the spacing, 2xn, between symmetric pairs of nodal lines (as shown in the 4. Explain why the slope of the graph represents the wavelength of the laser. diagram) for the first five pairs of nodal lines. 4. Measure the distance L, from the diffraction grating to the screen. 5. Create a data table in Graphical Analysis like the one below. 5. How good is your wavelength calculation? Does your value fall within the n - 2 accepted range? Why or why not? 2x (m ) x (m) 0_006 0.003 0 015 2840 . 9 0.018 0.009 0- 045 8527.7 6. Compare your results with those obtained by other groups. Aside from 0_030 0. 015 0.0075 1 4204.5 human error, why can you not expect all groups in your class to obtain the 0- 042 0 -02 0-0105 /19 9 986. 36 same wavelength values? |0.054 0.037 0- 0135 25568- 182 L= 2m d= 1.76*10#m
