Section 2: NIANIPULATING THE NIATH Write a single proportionality that sunnnarizes all the ndings from Section 1. Move the barrier towards the source {increase L] and observe the expected change in the fringe pattern. Now restore the spacing of the initial setup by changing on]: the slit separation. Do not move the barrier and do not change the source color. a. How did you succeed? b. How does the proportionality support this solution? Restore the slit separation to the initial set up value (13'50 run) and do not change the position of the barrier. The pattern is once again as observed above. Now restore the spacing of the initial setup by changing onlg the wavelength of the source. Do not move the barrier and do not change the slit separation. a. How did you succeed? b. How does the proportionality support this solution
