Select the 'WRONG' statement out of the following. (a) Electromagnetic waves do not require any medium for their propagation. (b) Electromagnetic waves can travel through vacuum with speed of light (c) Material medium is necessary for propagation of electromagnetic waves. (d) Electromagnetic waves are transverse in nature.

Answer: (c). EM waves are self-sustaining oscillating E and B fields, so they need no material medium. They travel through vacuum at c = 3× 10⁸ m/s and are transverse, so (a), (b), (d) are true. Statement (c) says a medium is necessary, which is false. So the answer is (c).

Nature of EM Waves & Wave Equation

Select the 'WRONG' statement out of the following.

Show answer and solution

Answer: (c)

EM waves are self-sustaining oscillating $\vec{E}$ and $\vec{B}$ fields, so they need no material medium.
They travel through vacuum at $c = 3\times 10^{8}\ \text{m/s}$ and are transverse, so (a), (b), (d) are true.
Statement (c) says a medium is necessary, which is false.
So the answer is (c).
