Outside the Electromagnetic Spectrum

AI Thread Summary
Electromagnetic (EM) radiation cannot exist outside the EM spectrum, as the spectrum encompasses all forms of EM radiation. There are no defined frequencies lower than radio waves or higher than gamma rays; the spectrum theoretically extends from zero to infinity. The discussion clarifies that this limitation is not due to a physical law but rather a matter of definition within the context of electromagnetic nature. The concept of subradio or supergamma frequencies does not apply, as all radiation falls within the established spectrum. Understanding these boundaries is essential for grasping the nature of EM radiation.

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.
 
This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...
Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'
Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
