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?
