In Young's double-slit experiment, light was first passed through a narrow single slit before going on to the double-slits. The reason for the first slit was
A. to ensure a constant phase relationship between the interfering light waves. B. to polarize the light. C. to screen out all wavelengths except those in the visible light spectrum. D. to reduce the brightness of the light so the interference pattern could be seen.
