The property which is not of an electromagnetic wave travelling in free space is that:

Options

  1. AThe energy density in electric field is equal to energy density in magnetic field
  2. BThey travel with a speed equal to 1μ0ε0\frac{1}{\sqrt{\mu_0 \varepsilon_0}}
  3. CThey originate from charges moving with uniform speed
  4. DThey are transverse in nature

Correct answer

C. They originate from charges moving with uniform speed

Step-by-step solution

The EM waves originate from an accelerating charge. The charge moving with uniform velocity produces steady state magnetic field.
