Light = small m WE CAN USE IT !!!

If I understand well, if you have electrostatic field detector it will sense field earlier than wave reaches it. Object charged by square wave will propagate that field faster when stop charging. That implies that square "wave" travels instatenously, and sinusoidal wave travels at speed C . It doesnt sound logical

At great distances ( and subsequently greater field strengths) such may be testable, but as it stands in earth conditions, this might prove difficult. Remember that the response time of your 'detector' is also constricted to the velocity of "c".

Exist Two type EM RADIATION

STATIC and MOTION

sometimes velocity is very very important

m --V-->           M



when small m is moving V

and  is hiting big mass M You can hear wave ( sound  )





electron --->     <<< EM WAVE 



when electron is hiting EM wave You can SEE wave not hear wave

( it is not sound but it is very similar mechanism electron is exchanging P=M*V with light )



electron = big M

EM wave = small m  SPEED IS HUGE !!!
EVERYTIME WHEN ELECTRON IS HITING EM WAVE WE HAVE NEW WAVE



SUN ------MOON ----------------------------EARTH

please preapare desk ( please make double slits in desk )

Do you see many lines ? BUT MOON IS NOT INSIDE TWO SLITS AT ONE TIME  ? !!!!



THIS WHAT WE HAVE IN BOOKS = ONE BOG FICTION

please study NEWTON   but AGAIN ( important is body Size  B area is much more biger compare to A area )
and DYNAMICA PREASURE not statica

 DO WE SEE CZERENKOW's RADIATION ?

Each body that is moving making EM wave consumption

All this wondering gives final question. What is speed of exiting electron in FEL lasers in function of speed of ongoing electrons? What is Δv of entry electron compared to exiting electron? From data known on relativistic dopler effect electron doesn't lose speed.
My expectation is that Δv is 0. FEL laser gives monochomatic light. It is possible only if electron don't losse own speed during travel trough undulator!
So to quote wiki -> _{The transverse acceleration of the electrons across this path results in the release of photons (synchrotron radiation), which are monochromatic but still incoherent}
