A stream of electrons travelling at 40.0 km/s is incident on a single slit of width 500.0 nm.

(a) What is wavelength of the electrons?

(b) What is the spacing between adjacent minima in the resulting diffraction pattern if there is a screen 1.20 metres behind the slit?

(c) If the electrons were instead sent one at a time (but still many sent), rather than as a stream, would a diffraction pattern still be seen? Why or why not?

(d) If these electrons were ejected from a piece of Titanium with a work function of 3.84 eV via the photoelectric effect, what was the wavelength of the light used?

A beam of electrons is incident on a single slit whose width could be varied with as high precision as we like. Assuming that we would like to resolve 1% difference in momentum, please estimate the slit width that would be necessary to resolve the interference pattern of the electrons if their kinetic energy is (a) 0.02 MeV, (b) 0.8 MeV and 120 MeV? Hint: one does not need to do a detailed interference pattern analysis here, just use your...

Width of Peak (cm): 1.6 Width of Slit for Single Peak: 2.3 The width of the center peak (w) can be calculated using the equation w = 2λL/ a where a is the width of the slit. Use this equation to determine the width of the slit that caused the diffraction pattern. Show your work. I am confused as to what I am finding since I do not have L. I have going backwards λL = 1.84. If someone could...

A single-slit diffraction pattern is formed on a distant screen. If the width of the single slit through which light passes is reduced, what happens to the width of the central bright fringe? Assume the angles involved remain small.            The central bright fringe becomes wider.                     The central bright fringe remains the same size.                     The effect cannot be determined unless the distance between the slit and the screen is known.                     The central bright fringe becomes narrower.

Consider a beam of electrons in a vacuum, passing through a very narrow slit of width 2.00?m. The electrons then head toward an array of detectors a distance 1.080m away. These detectors indicate a diffraction pattern, with a broad maximum of electron intensity (i.e., the number of electrons received in a certain area over a certain period of time) with minima of electron intensity on either side, spaced 0.508cm from the center of the pattern. What is the wavelength ?...
