In young's experiment, coherent light passing through two slits separated by a distance d produces a pattern of dark and bright areas on a distant screen. if instead you use 10 slits, each the same distance d from its neighbor, how does the pattern change? a) the bright areas move farther apart. b) the bright areas move closer together. c) the spacing between bright areas remains the same, but the bright areas become narrower. d) the spacing between bright areas remains the same, but the bright areas become broader.
