Which statement comparing diffraction to double slit
interference patterns is true?
Select one:
a.
In double slit interference, the position of the minima (dark
spots) are well known in this experiment. In comparison, in
diffraction, it is the position of the maxima (bright spots) that
are well known.
b.
The aperture of the slits determines the maxima (bright spots)
positions in both diffraction and double slit interference.
c.
In both double slit interference and diffraction, the distance
between the slits determines the pattern seen on the screen.
d.
The central bright spot of a diffraction light pattern is twice
as wide as the other bright spots. By comparison, double slit
interference pattern has a central bright spot that is the same
width as its other bright spots.
