The property which is not of an electromagnetic wave travelling in free space is that :
Updated On: Dec 4, 2024
- they are transverse in nature.
- the energy density in electric field is equal to energy density in magnetic field.
- they travel with a speed equal to \(\frac{1}{\sqrt{\mu_0\epsilon_0}}\).
- they originate from charges moving with uniform speed.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Electromagnetic waves are generated by charges undergoing acceleration, not by charges moving with uniform speed. All other properties are characteristics of electromagnetic waves:
- Energy densities of electric and magnetic fields are equal.
- Their speed is $\frac{1}{\sqrt{\mu_0 \epsilon_0}}$.
- They are transverse waves.

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
