Unformatted text preview: –4 kg crawls across a table at a speed of 2 mm/s. Compute the de Broglie wavelength of the fly and compare it to the size of a proton (about 1 fm, 1 fm = 10 –15 m). 3. An 81kg student who has just studied matter waves is concerned that he may be diffracted as he walks through a doorway that is 81 cm across and 12 cm thick. (a) If the wavelength of the student must be about the same size as the doorway to exhibit diffraction, what is the fastest the student can walk through the doorway to exhibit diffraction? (b) At this speed, how long would it take the student to walk through the doorway? 4. What are the de Broglie wavelengths of electrons with the following values of kinetic energy? (a) 1.0 eV; (b) 1.0 keV....
