You illuminate a michelson interferometer with a helium-neon laser. the interference pattern is uniform – there are no stripes or rings. the laser has a wavelength of 632.8 nm. you move the mirror on the translation stage until the intensity of the interferometer output is maximum. you measure that the output intensity is i0 = 0.80 mw/cm2. then, you move the mirror on the translation stage by some additional amount \deltax. you observe that the output intensity drops monotonically to 0.63 mw/cm2 . what was the value of \deltax? (note the specification that the intensity falls monotonically means that the intensity never went to zero during your additional mirror displacement.)

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.
