Electromagnetic Spectrum Wavelengths

AI Thread Summary
The visible spectrum is unique primarily because it is the only part of the electromagnetic spectrum that humans can perceive. All portions of the electromagnetic spectrum, including infrared and ultraviolet, possess distinct properties, but visibility is what makes the visible spectrum special. The variations across the electromagnetic spectrum are fundamentally based on differences in frequency and wavelength. Other segments of the spectrum also have unique characteristics, but they are not experienced by humans in the same way. Ultimately, the significance of the visible spectrum stems from human perception.

The question I have is a bit difficult to express.

The foundation of my question. Within the electromagnetic spectrum there is the visible spectrum. Broken down that has our individual colors that we see.

Do all portions of the electromagnetic spectrum have special properties such as this that are not as widely addressed or is this a special group classification because as humans we can see this spectrum?

Thanks

It's only special because we can see it. The only thing that changes across the electromagnetic spectrum is the frequency/wavelength.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
