97.29: A student performs an experiment similar to Young’s Dpl:mb. m4df-6d i1/ +kv8s w:r talgljouble Slit Experiment. Coherent light passes through two narrow slits and produces a pattern of alternating bright and dark lines on a screen. Which of the following would cause the bright lines on jd:fs lk8m1 pbi.v:6-4 /m+ l adtwgrlthe screen to be further apart?
I. Increasing the distance between the slits.
II. Decreasing the distance between the slits.
III. Decreasing the wavelength of the light.
