defence exam Army Havildar SAC Mock Test Series 2025 Physics Electromagnetic Waves The Traveling Electromagnetic Wave
In \(\vec E\) and \(\vec K\) represent electric field and propagation vectors of the EM waves in vacuum, then magnetic field vector is given by :
(ω - angular frequency):
1
\(\omega(\overline{\mathrm{E}} \times \overline{\mathrm{K}})\)
2
\(\omega(\overrightarrow{\mathrm{K}} \times \overrightarrow{\mathrm{E}})\)
3
\(\overline{\mathrm{K}} \times \overline{\mathrm{E}}\)
4
\(\frac{1}{\omega}(\overline{\mathrm{K}} \times \overline{\mathrm{E}})\)
