One can choose the psi wave component too. The intensity also depends  
on the number of photons, which is guided by the wavefunction. From  
this view, the intensity can also be constant despite of the varying  
em field.

You're still better than many others who simply assume the intensity  
to be constant without ever thinking or realising these *tricky*  
components. Just try to conduct PER on this concept, the findings  
should be interesting!
