In single slit experiment a mixture of red light (632 nm) and blue light (471 nm) shines on the single slit. The centers of the first order bright blue fringes lie at the outer edges of a screen that is located 0.500 m away from the slits. However, the first-order bright red fringes fall off the screen. By how much and in which direction (toward or away from the slits) should the screen be moved so that the centers of the first-order red fringes will just appear on the screen? (hint L2-L1 =?) Note: Answer should be in decimal notation should have three digits with units no space
