The student passes 633 nm laser light through a narrow slit and observes 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 bright central fringe is 35.0 mm. (a) How wide is the slit? (b) The intensity at the center of the pattern is 0. What is the intensity at a point on the screen 3.80 mm from the center of the pattern?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
