Outside the Electromagnetic Spectrum

arjose

Is it possible for EM radiation to exist outside the EM spectrum? I'm aware of the different frequencies at which energy can be radiated eg. radio, infrared, and gamma. But is it possible for objects to absorb or release energy at subradio or supergamma frequencies? Or is there a physical law that prohibits these phenomena?

Any feedback would be appreciated.

The EM spectrum encompasses all EM radiation, so by definition you cannot have EM radiation outside the EM spectrum.

Is there a physical law that creates this limitation or is it just a matter of technicality, where lower or higher frequencies are no longer defined as having electromagnetic nature? I'm just wondering whether those extremes fall into quantum energies or with dark energies.

No, it is just that there is no such thing as lower or higher frequencies. The EM spectrum goes from 0 to infinity, there is no frequency lower than 0 and no frequency higher than infinity.

Thanks. That clears it up.
