A beam of electrons hits a pair of slits spaced a distance d apart (center-to-center). The wavelength of the electrons is 23.8 nm. After traveling through the slits, the electrons form an interference pattern on a screen located a distance 0.750 m from the slits. If the center of the second 'bright' fringe occurs 2.30 cm from the center of the central bright fringe on the screen, what is the separation, d, between the slits?

How fast are the electrons traveling?

A beam of electrons moving at a speed of 8.4×106 m/s passes through a double-slit. The wavelength of these electrons is 8.677×10-11 m. A phosphorescent screen is placed 1.7 m behind the slits so that each time an electron hits the screen the spot where the electron hits will glow. Since electrons have a wave nature, the pattern of glowing spots forms an interference pattern on the screen. You measure the separation between the central bright fringe and the m=6...
