- 2. Red laser light (X=680 nm) is incident on two narrow, closely-spaced slits. The resulting pattern of bright and dark fringes is projected on a screen, and the centermost bright fringes are seperated by 2.0 cm. If the red laser is replaced with a green (A=500 nm) one, how would the spacing of the centermost fringes change? A. The centermost bright fringes will remain 2.0 cm apart B. The centermost bright fringes will get closer together C. The centermost bright fringes will get farther apart D. No bright fringes would be visibleDue to the wave nature of light shines on a single slit will produce a diffraction pattern. Green light 505nm is shined on a slit with width 0.490nm. a) find the width of the central maximum located 1.50 m from the slit in mm b) what is the width of the first order fringe in mmA flat screen is located 0.45 m away from a single slit. Light with a wavelength of 540 nm (in vacuum) shines through the slit and produces a diffraction pattern. The width of the central bright fringe on the screen is 0.046 m. What is the width of the slit?
