NEET (UG) 2024 — Question 41

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

Option A:
They are transverse in nature
Option B:
The energy density in electric field is equal to energy density in magnetic field
Option C:
They travel with a speed equal to $\frac{1}{\sqrt{\mu_{0} \varepsilon_{0}}}$
Option D:
They originate from charges moving with uniform speed
Correct

Answer: D

Step-by-step solution

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