Electromagnetic waves consist of periodically oscillating electric and magnetic vectors:
- Ain mutually perpendicular planes but vibrating with a phase difference of $\pi$.
- Bin mutually perpendicular planes but vibrating with a phase difference of $\frac{\pi}{2}$.
- Cin randomly oriented planes but vibrating in phase.
- Din mutually perpendicular planes but vibrating in phase.

View Solution$A$ plane electromagnetic wave of wavelength $3.0 \ m$ travels in vacuum along the positive $X$-axis. The electric field of amplitude $300 \ Vm^{-1}$ oscillates parallel to the $Y$-axis. Then the intensity of the wave is $(\mu_0 = 4\pi \times 10^{-7} \ Hm^{-1}, c = 3 \times 10^8 \ ms^{-1})$ (in $Wm^{-2}$)
The peak value of the magnetic field of an electromagnetic wave moving in a magnetic field is $20 \, nT$. The peak value of the electric field intensity is ..... $V/m$.
