Light of a particular wavelength shines on a single slit of width 1.150e-4 m, creating a diffraction pattern with the first dark fringe at an angle of 0.224° from the centerline. If the same light shines instead on two even narrower slits, the interference pattern has its first dark fringe (the one adjacent to the central maximum) at the same angle. What is the distance between the centers of the two slits? Answer in meters.
For the Atwood's machine, suppose the masses have an initial speed of v = 0.22 m/s and that m2 is moving upward. How high does m2 rise above its initial position before momentarily coming to rest, given that m1 = 3.5 kg and m2 = 3.1 kg.
