Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

No energy principle in electron magnetohydrodynamics EMHD - any stationary closed configuration is neutrally stable. Best regards.

Victor Ilgisonis

Sometimes it can work. See, e.g., http://epsppd.epfl.ch/Maas/web/pdf/p2083.pdf

Thanks to you all for replying, But still I am not getting how it can be understand that there is no energy principle?

"No energy principle" means that one cannot investigate stability just looking at the energy variation. However, sometimes one can - see the reference I have mentioned. By the way, for plasma with flows, the energy principle works badly even in the frame of conventional MHD.
