Abstract: In both the equations for matter and light wave propagation, the momentum ofthe electromagnetic fields Pe reflects the relevant em interaction. As a reviewof some applications of wave propagation properties, an optical experimentwhich tests the speed of light in moving rarefied gases is described. Moreover,Pe is also the link to the unitary vision of the quantum effects of theAharonov-Bohm AB type, which provide a useful quantum approach for the limitof the photon mass mph. A bench-top experiment based on effects of the AB typethat exploit new interferometric techniques, is foreseen to yield the limit mph= 10^-54 g, a value that improves upon the results achieved with otherapproaches.
