Some details of elementary particles may need to be probed on distance scales as small as 10-18 m. Calculate the kinetic energies of an electron and a proton necessary to probe details this small. (Hint: See Problem 4, but we don’t need to divide by the factor of 10 to determine the wavelength.)
Problem 4
To probe another particle with linear dimensions D, the wavelength of the probing particle must be λ ≤ D. To learn details, the wavelength should be substantially less, perhaps as small as 0.10D. Calculate the kinetic energies of an electron and a proton needed to probe the details of a neutron. Assume the diameter of the neutron is 1.5 fm.
