Electromagnetic Waves – E and B Amplitudes
1 question, with its answer.
-
In a plane electromagnetic wave travelling in free space, the electric field component oscillates sinusoidally at a frequency of $2.0\times10^{10}\ Hz$ and amplitude $48\ Vm^{-1}$. Then the amplitude of oscillating magnetic field is: (Speed of light in free space $=3\times10^8\ ms^{-1}$)
$B_0=\frac{E_0}{c}=1.6\times10^{-7}\ T$.
$B=\frac{E}{C}=\frac{48}{3\times10^8}=16\times10^{-8}=1.6\times10^{-7}\ T$
That is every question in Electromagnetic Waves – E and B Amplitudes.
