Question

Experiment 3 1. Student passes 633 nm laser light through a narrow slit and observe the diffraction pattern on a screen 7.00 m away. The distance on the screen between the centers of the first minima on either side of the central bright fringe is 35.0 mm. (a) How wide is the slit? (b) The intensity at the center of the pattern is lo. What is the intensity at a point on the screen 3.80 mm from the center of the pattern? 2. (a) The intensity at the center of a single slit diffraction pattern is lo. 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?
