What is the condition of a construction interference (bright fringe) in two slit experiment? A. The path difference between two waves from both the slits should be an integral multiple of wavelength (i.e., 0, ±4, ±24, ±3A..). B. The path difference between two waves from both the slits should be half-odd integral multiple of wavelength (e.g., ±N2, ± 3/2, + 5N2..). C. There should be no path difference at all for constructive interference to form. D. The slit separation should be very small.
