FRET is analogous to near-field communication, in that the radius of interaction is much smaller than the wavelength of light emitted. In the near-field region, the excited chromophore emits a virtual photon …

While fretting today usually involves a concern that is figuratively eating at someone, fret has older senses that apply to literal eating. Fret comes from the Old English verb fretan, “to devour,” which …
