Consider the following proposed modifications to a double-slit experiment. Each begins with identical initial conditions.
I. Double the wavelength of the light and simultaneously double the slit separation.
II. Halve the slit separation while keeping all other parameters the same.
III. Double the screen distance while halving the wavelength.
Rank the predicted fringe spacing produced after each modification, from largest to smallest.
(a) I > II > III
(b) II > I > III
(c) II > I = III
(d) III > I > II
