If $E$ and $B$ be the electric and magnetic field vectors of electromagnetic waves, the direction of propagation of electromagnetic waves is that of-
1 $\mathrm{E}$
2 $\mathrm{B}$
3 $\mathrm{E} \times \mathrm{B}$
4 $\mathrm{B} \times \mathrm{E}$
Explanation:
C If $\vec{E} \& \vec{B}$ are the electric \& magnetic field vector of EM wave then $\vec{E} \& \vec{B}$ are perpendicular to each other, then direction of propagation of EM wave . is $(\overrightarrow{\mathrm{E}} \times \overrightarrow{\mathrm{B}})$.

Electromagnetic waves are produced by
1 Charges at rest only
2 Changes in uniform motion only
3 Accelerated or decelerated changes only
4 An unchanged stable particle at rest
Explanation:
C The EM wave are produced by only when an electric charge accelerated or decelerated. The change in the electric and the magnetic field of the charge on acceleration or deceleration is manifested in the form of electromagnetic waves.

Which of the following has/have zero average value in a plane electromagnetic wave?
1 Both magnetic and electric fields
2 Electric field only
3 Magnetic field only
4 Magnetic energy
Explanation:
A Both electric \& magnetic field in EM wave are sinusoidal in nature $\&$ the average value of sinusoidal wave is zero. Hence, both electric and magnetic field have zero average value in a plane EM wave.
