Electrons are accelerated through a 20 V potential difference, producing a monoenergetic beam. This is directed at a double-slit apparatus of 0.010 mm slit separation. A bank of electron detectors is 10 m beyond the double slit. With slit I alone open, 100 electrons per second are detected at all detectors. With slit 2 alone open, 900 electrons per second are detected at all detectors. Now both slits are open.
(a). The first minimum in the electron count occurs at detector X. How far is it from the center of the interference pattern?
(b). How many electrons per second will be detected at the center detector?
(c). How many electrons per second will be detected at detector X?
