Part II: Determine Wavelength of the He-Ne Laser Use your sketch of Pattern D (a = 0.16mm) to measure the distance from the center of the central maxima to the center of each minima. Record the minima number, m, and the height of the minima, ym, for eight successive minima to one side of the central maximum. Using Eq. 5, calculate Am for each value; these should be roughly the same. Compute the average wavelength value, ХЕХ. Question 3. Does the known wavelength ATH (633 nm) agree with the experimental wavelength you calculated above? Calculate the %D Question 4. Find an expression for , in terms of a, m, 0, ym, and L, starting with Eq. 3 and not using the small-angle approximation. Question 5. What contributes to your error in this experiment? How would these errors affect the results? Be specific. CALIFORNIA STATE UN
