Question
The property which is not of an electromagnetic wave travelling in free space is that:
Options
A.They travel with a speed equal to $\frac{1}{\sqrt{\mu_{0}\varepsilon_{0}}}$
B.They originate from charges moving with uniform speed
C.They are transverse in nature
D.The energy density in electric field is equal to energy density in magnetic field
Solution
Sol. [Key Concept: Properties of EM waves travelling in free space]
The EM waves originate from an accelerating charge. The charge moving with uniform velocity produces steady state magnetic field.
