Perhaps there need not be "degrees of quantumness" ("Degrees of Quantumness: Shades of gray in particle-wave duality," SN: 5/12/07, p. 292). As the beams pass increasingly closer to the surface, the plate will induce a small (but increasingly larger) spread of energies (hence wavelengths) in the electrons within the beam, possibly explaining the "smearing out" of the fringes in the interference pattern.

Peter Sonnentag of the University of Tubingen in Germany says that the loss of energy is tiny: less than 0.1 percent. Moreover, Sonnentag says that the change in energy could account for a change only infringe spacing, not infringe visibility.--D. CASTELVECCHI
