Figure 2.39 shows a photograph that illustrates the kind of interference fringes that can result when white light, which is a mixture of all colors, is used in Young's experiment, Except for the central fringe, which is white, the bright frings are a rainbow of colors. Why does Young's experiment separate white light into the constituent colors? In any group of colored fringes, such as the two singled out in the figure, why is red farther out from the central fringe than green is? And finally, why is the central fringe white rather than colored?  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V04_C02_S01_023_Q01.png" width="80%"
