When two wave functions are in perfect phase = constructive interference(adsbygoogle = window.adsbygoogle || []).push({});

when the phase difference is half (the wavelength) = destructive interference

What happens when the phase difference ismore than one wavelengthin case of:

Case 1: single particle interference

Case 2: two-photon (i.e. a pair of entangled photons) interference

i.e say twice the wavelength

How about phase difference thrice the wavelength?

in short: does single particle interference happen if the phase difference is more than one wavelength?
