Measuring the frequency of the e.m. oscillations in the em. wave

AI Thread Summary
An observer positioned in a plane sinusoidal and polarized electromagnetic wave can measure the frequency of the wave by erecting a metallic antenna perpendicular to the direction of propagation. This setup generates a sinusoidal potential difference across the antenna that matches the frequency of the electromagnetic wave. The discussion highlights that the method is valid for measuring frequency, regardless of the polarization type—linear, circular, or elliptical. The impact of different polarizations on the measurement is acknowledged but not elaborated upon. Overall, this method is confirmed as an effective way to determine the frequency of the electromagnetic wave.

Consider please that an observer is located in a plane sinusoidal and polarized e.m. wave. He erects a metalic antenna normal to the direction of propagation. A sinusoidal potential difference appears between the two ends of the antenna having the same frequency as the e.m. has. Is that a correct way to measure the frequency?

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...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
