A simple enough question not to need a summary - I hope

Main Question or Discussion Point

The classical picture of the electromagnetic wave has electric and magnetic field oscillations which give the wavelength of the light. In the quantum picture, is the wavelength of the (de Broglie) wave function of the photon the same thing?

Is it suprising that something normally taken to be non physical (the wavefunction regarded as a probability amplitude) has a physical manifestation (electric / magnetic field oscillations)? What's the deeper reason behind this? Are there any other instances where classical and quantum are the same in this way?

Matter waves have no magnetic and electric fields so no. They are not the same thing as electromagnetic waves.
Matter waves are inferred whereas electromagnetic waves can be and are measured directly.

I think you are reading too much into this. Are electromagnetic wavelength and water wavelength the same thing?
