This question is modern physics from the waves and particles chapter:
An electron beam strikes a barrier with a single narrow slit, and the electron flux – number of electrons per unit time per unit area – detected at the very center of the resulting intensity pattern is F_1. Next, two more identical slits are opened equidistant on either side of the first and equally “illuminated” by the beam. What wil be the flux at the very center now? Does your answer imply that ore than three times as many electrons pass through three slits than through one? Why or why not?
Electrons with an energy of 0.610 eV are incident on a double slit in which the two slits are separated by 60.0 nm.
a) What is the de Broglie wavelength (in nanometers) of these electrons?
b) What is the angle between the two second-order maxima in the resulting interference pattern?
I really appreciate the help on this question. I've been stumped on it.
Could an experiment involving electron diffraction be conducted with three or four slits? Employing a grating with several slits? What type of outcomes might you anticipate with a grating? Would this violate the uncertainty principle? Explain.

- 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.)arrow_forwardConsidering the double slit experiment for electrons, (a) explain why we can observe an interference/diffraction pattern if we place a detector (able to detect where the electron arrives) on a bulkhead located at a certain distance from the slits. (b) from the Heisenberg indeterminacy principle, explain why this pattern disappears if we also put a detector on one of the slits (discovering through which slit the electron passed).arrow_forwarda) In a double-slit experiment, a stream of electrons with speed v = 10 m/s is aimed at two parallel slits. On the screen one meter behind the slits an interference pattern is observed in the number of electrons arriving at different points on the screen. The distance between the first and the second intensity maxima is 1 cm. Find the distance between the slits. b) What is the distance between the first and the second maxima in the interference pattern, if we perform the double-slit experiment with footballs (mass 0,4 kg) moving at speed 10 m/s? Let's assume the slits are 1 m apart, and the screen is 10 m behind the slits. Is it possible to observe interference of footballs?arrow_forward
- Consider electrons incident on a double slit apparatus.

Give your answer in Angstrom (10-10 m, for example, if the answer is 1.6x10-10 m, then write 1.6 as your answer). This should give you a good idea why one can use a crystal lattice with an average interatomic distance of around 10-10 m to observe electron diffraction.arrow_forwardConsider an electron in an infinite potential well size of a=0.1 nm. What is the ground energy of the electron? What is the energy required to put the electron at the third energy level?Calculate the wavelength of the photon that would provide this required energy?

The closest stars are 4 light years away from us. How far away must you be from a 881 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.arrow_forwardCalculate the wavelength corresponding to an electron with the energy of 95 eV (kiloelectronvolt).

- You are working as a demonstration assistant for a physics professor. She wants to demonstrate to her students the buildup of the interference pattern for single electrons passing through a double slit. Her source of electrons will be a certain vacuum tube, in which electrons evaporate from a hot cathode at a slow, steady rate and accelerate from rest through a potential difference of 45.0 V. After being accelerated, they travel through a fieldfree and evacuated region before they pass through the double slits and fall on a screen to produce an interference pattern. To ensure that only one electron at a time is passing through the slits, she wants the electrons to be separated in space by d 5 1.00 cm (perpendicular to the barrier containing the slits) as they approach the slit. She asks you to determine the maximum value for the beam current that will assure that only one electron at a time passes through the slits.arrow_forwardIn the experiment by Jönsson, 50-keV electrons impinged on slits of width 500 nm separated by a distance of 2000 nm. The observation screen was located 350 mm beyond the slits. What was the distance between the first two maxima?arrow_forwardA beam of electrons is accelerated from rest and then passes through a pair of identical thin slits that are 1.25 nm apart. You observe that the first double-slit interference dark fringe occurs at +-18.0 from the original direction of the beam when viewed on a distant screen. (a) Are these electrons relativistic? How do you know? (b) Through what potential difference were the electrons accelerated?arrow_forward
