Frequency & Wavelenght of EM wave!
Hi..on some other thread i found this link showing animation of propagation EM wave:
http://www.molphys.leidenuniv.nl/monos/smo/index.html?basics/light_anim.htm
it has cleared my one doubt, because i used to think that EM wave is like an invisible line in air which moves up and down like sinusoidal manner. But it actually a variation in electromagnetic field.
But then my question is:
the frequency of the EM wave is the frequency of electric & magnetic field variation( as AC voltage)?
and how wavelength is measured since there is no(physical) peaks to measure distance between?
