In Young’s experiment, coherent light passing through two slits ( S 1 and 2) produces a pattern of dark and bright areas on a distant screen. If the wavelength of the light is increased, how does the pattern change? A. The bright areas move closer together B. The bright areas move farther apart . C. The spacing between bright areas remains the same, but the color changes. D. any of the above, depending on circumstances E. none of the above
