Two narrow slits are utilized to produce a double-slit interference pattern with monochromatic light (λ = 680 nm). The slits are separated by 0.70 mm, and the interference pattern is projected onto a screen 5.5 m away from the slits. What is the distance among two nearby bright fringes on the screen and what is the distance among two nearby dark fringes on the screen? Assume the fringes are near the center of teh interference pattern.
