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 modified oscilloscope is used to perform an electron interference experiment. Electrons are incident on a pair of narrow slits 0.060 0 um apart. The bright bands in the interference pattern are separated by 0.400 mm on a screen 20.0 cm from the slits. Determine the potential difference through which the electrons were accelerated to give this pattern.A single beam of electrons shines on a single slit of width 8.7nm. A diffraction pattern (of electrons!) is formed on a screen that is 3.9m away from the slit. The distance between the central bright spot and the first minimum is 5.7cm.What is the kinetic energy (keV, i.e. kilo electron-Volts) of the electrons?Make use of the small angle approximation.A beam of electrons with kinetic energy 45 keV is shotthrough two narrow slits in a barrier. The slits are a distance 2.0 x 10-6 m apart. If a screen is placed 45.0 cm behind the barrier, calculate the spacing between the “bright” fringes of the interference pattern produced on the screen
- This question relates to the practicality of searching for intelligent life in other solar systems by detecting their radio broadcasts (or aliens find us from ours). The closest stars are 4 light years away from us. How far away must you be from a 460 kHz radio station with power 50.0 kW for there to be only one photon per second per square meter? Assume that the photons spread out spherically. The area of a sphere is 4??24πr2. b) How many lightyears away is this?Electrons with an energy of 0.842 eV are incident on a double slit in which the two slits are separated by 40.0 nm.

Would the uncertainty principle be violated? Explain.For a given accelerating voltage, an electron microscope has a certain theoretical resolution. Suppose that instead of a beam of electrons you used a beam of protons, with the same accelerating voltage. How would this affect the theoretical resolution?For x rays with wavelength 0.0300 nm, the m = 1 inten- sity maximum for a crystal occurs when the angle u in Fig. is 35.8°.
