Why do the two slits need to be small in order for an interference pattern to occur?
Why do the two slits need to be small in order for an interference pattern to occur? The very short wavelengths of visible light explain why interference effects are observed only in special circumstances—the spacing between the sources of the interfering light waves must be very small to separate regions of constructive and destructive interference. […]
