What is the amount of energy required to change path/trajectory of a photon by an infinitesimal amount?(adsbygoogle = window.adsbygoogle || []).push({});

In a single particle (double slit) interference, the photons land up on one of the interference fringes. (when no-which-way)

If we were to place a magnet to try to slightly change the path of the photon, (say from one of the fringes to a blob in-between)how much of the electromagnetic energy would be required? (relative to the one quanta of energy of the photon)

alternatively

are there any energy effects involved in (single particle) interference?

....the path of the photon is getting changed (after all, atleast per some of the interpretation of QM) from fringe to no-fringe co-ordinates
