Q. The property which is not of an electromagnetic wave travelling in free space is that;
A) they travel with a speed equal to $\frac{1}{\sqrt{\mu_0\epsilon_0}}$
B) they originate from charges moving with uniform speed.
C) they are transverse in nature.
D) they energy density in electric field is equal to energy density in magnetic field.
