1)In a Young’s double-slit experiment that uses electrons, the angle that locates the first-order bright fringes is θA = 2.5 × 10-4 degrees when the magnitude of the electron momentum is pA = 1.2 × 10-22 kg*m/s. With the same double slit, what momentum magnitude pB is necessary so that an angle of θB = 5.0 × 10-4 degrees locates the first-order bright fringes?
pB =

2) An electron, traveling at a speed of4.53 × 107 m/s, strikes the target of an X-ray tube. Upon impact, the electron decelerates to one-quarter of its original speed, emitting an X-ray in the process. What is the wavelength of the X-ray photon?
