If a sheet containing a single slit is heated (without damaging it)and therefore expands,what happens to the angular location of the first-order diffraction minimum?
A)It moves toward the centerline.
B)It moves away from the centerline.
C)It doesn't change.

When the sheet containing a single slit is heated and expands, the slit width increases. As the slit width increases, the diffraction pattern becomes narrower and the diffraction minimum moves toward the centerline. Therefore, the angular location of the first-order diffraction minimum moves toward the centerline.
