The discussion centers on the optical phenomenon observed during an eclipse, specifically regarding the visibility of the sun and moon shapes through gaps in leaves. Participants clarify that this effect is due to classical physics, particularly the pinhole effect, rather than any quantum mechanical processes. The consensus is that light behaves as a classical electromagnetic wave in this context, and decoherence does not play a role in the visibility of the shapes. The thread concludes with a definitive stance against the involvement of quantum mechanics in this phenomenon.
PREREQUISITESStudents of physics, educators in optics, and anyone interested in the classical interpretation of light phenomena during eclipses.
quantuminternet said:I'm saying it is pinhole + decoherence.
DrClaude said:In any case, there is nothing quantum mechanical taking place here.
No. This is a completely classical phenomenon that as nothing to do with quantum mechanics, photons, or decoherence.quantuminternet said:Is the reason you can make out the shape of the sun and the moon is because the gaps between the leaves cause the light to be photons instead of waves?
