Electrons go through a single slit 150 nm wide and strike a screen 24.0 cm away. You find that at angles of +/- 20.0 degrees from the center of the diffraction pattern, no electrons hit the screen but electrons hit at all points closer to the center.
(a) How fast were these electrons moving when they went through the slit?
(b) What will be the next larger angles at which no electrons hit the screen?
A beam of electrons strikes a double slit, with the slit separation of 102 nm. The first-order diffraction maximum is seen at an angle of 5 degrees away from the beam's direction. What was the speed of the electrons? (Hint: First determine the wavelength of the electrons using the double-slit interference equations from the optics unit. Then use that to determine the speed of the electron.)
A beam of 40 eV electrons traveling in the+x-directionpasses through a slit that is parallel to the y-axis and5.0 mm wide. The diffraction pattern is recorded on a screen 2.5 mfrom the slit. (a) What is the de Broglie wavelength of the electrons?(b) How much time does it take the electrons to travel from the slit tothe screen? (c) Use the width of the central diffraction pattern to calculatethe uncertainty in the y-component of momentum of an electronjust after it has passed through the slit. (d) Use the result of part(c) and the Heisenberg uncertainty principle [(Eq. 39.29) for y] toestimate the minimum uncertainty in the y-coordinate of an electronjust after it has passed through the slit. Compare your result to thewidth of the slit.
