How long is an electromagnetic wave? Can it be of any length depending on the source? or is it some integral/even multiple of the wavelength? Also, can an electromagnetic wave have varying magnitudes of electric and magnetic fields (at varying distances on the wave) depending on varying frequency of oscillations of the source? and how does it terminate?
(Note that I haven't read the chapters on transverse waves yet, but I think I have an idea of it)
