The intensity at the center of a single – slit diffraction pattern is 0. What is the intensity at a point in the pattern where there is a 68.0 radian phase difference between wavelets from the two edges of the slit? (b) If this point is 9. 00° away from the central maximum, how many wavelengths is the slit wide?
