Unformatted text preview: average To begin the experiment, set up the laser system aligning the diffraction card so that the laser shines through slit A. Sketch the resulting diffraction pattern, then measure and record the distance from the diffraction card to the wall (L). The width of slit A of the diffraction card is 4 x 105 meters (d). Next, begin measuring the distances from the central maximum to each of the dark spots (y). Then, calculate the experimental value for the wavelength of the laser using the equation given above. Compare the experimental value with the actual value for the wavelength (λ = 633 x 109 m) by finding the percent error between the two. Using the calculated wavelength value, repeat the procedure to measure the slit width of slit B or slit C on the diffraction card. Compare the calculated value to the actual value of the corresponding slit....
