Question

Quizplus · Accepted Answer

The range of an electromagnetic interaction is given by the Compton wavelength, which is λ = h/(mc), where h is Planck's constant, m is the mass of the particle involved, and c is the speed of light. In this case, the particle involved is the virtual photon. Using the given energy, we can calculate the mass of the virtual photon using E = mc^2, which gives m = E/c^2 = 1.1 F1F1F1S1F1F1F10 10^-20 J/c^2. Substituting this into the Compton wavelength formula, we get λ = h/(mc) = h c/(1.1 F1F1F1S1F1F1F10 10^-20 J) ≈ 3 µm. Therefore, the answer is B.
