Problem 1

Comparison between Graphs 1 and 2 :
(a) What parameters of the experiment were kept constant in producing Graphs 1 and 2 ? What parameters were changed?
(b) Compare the locations of the first minima of diffraction $(m=1$ and $m=-1$ on Graph 1) to the same positions along the $x$ -axis on Graph 2. Are the positions also minima in Graph 2?
(c) In Graph 2, how many interference fringes (bright) are in between the locations of $m=1$ and $m=-1$ of the single-slit pattern?
