2. When light shines through a thin slit with width w, it creates a pattern of bright and dark spots. The angle between a line connecting the slit +1, +2, +3, ... The angle can and the center of the pattern and one connecting the slit with a dark spot follows w sin(0m) = m where m = also be determined from tan(em) = ym/D. The lab writeup makes the claim that one can make a plot of ym vs m and obtain a slope equal to AD/w. a) What are the assumptions behind this claim? b) Do a derivation to show the claim is reasonable. Do parts a) and b) in a text cell below
