The property which is not of an electromagnetic wave travelling in free space is that:
(1). They are transverse in nature
(2). The energy density in electric field is equal to energy density in magnetic field
(3). They travel with a speed equal to \(\frac{1}{\sqrt{\mu_0\epsilon_0}}\)
(4). They originate from charges moving with uniform speed
