1.Two slits spaced 0.230 mm apart are 0.980 m from a screen and illuminated by coherent light of wavelength 660 nmnm. The intensity at the center of the central maximum (θ=0∘)is I0. a)What is the distance on the screen from the center of the central maximum to the point where the intensity has fallen to I0/2?Express your answer with the appropriate units.
