Student passes 633 �� laser light through a narrow slit and observe the diffraction pattern on a screen 7. 00 � away. The distance on the screen between the centers of the first minima on either side of the central bright fringe is 35.0 ��. (a) How wide is the slit? (b) The intensity at the center of the pattern is �R. What is the intensity at a point on the screen 3.80 �� from the center of the pattern?
