- Andswer is E can someone explain?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.
