Unformatted text preview: the large, medium, and small slits I was able to see, 20, 15, and 5 bright fringes for each respectively. 2.) Check calculations sheet attached. Yes, my answers appear reasonable because the slits get smaller as the slits get larger. 3.) The overall pattern spread out to a parallel pattern for each slit. If the slits were turned 90 degrees, the slits would still be parallel but in a line from top to bottom. C 1.) 2.) d=0.4262 mm The answer does seem reasonable because the distance looked < 1mm. 3.) The orientation of the linear fringes are parallel to the line connecting the center of the pinholes. If the slide was rotated 90 degrees, then the circle-like image would still have the same outline but the slits would be horizontal instead of vertical. D 1.)Yellow was diffracted through the largest angle, and purple was diffracted through the smallest angle. This is in agreement with section 2 because the middle color is the brightest....
