AP EAMCET · PHYSICS · Electromagnetic Waves
If \(\vec{E}\) and \(\vec{B}\) are the electric and magnetic field vectors of an electromagnetic wave, then the direction of propagation of the electromagnetic wave is
- A along the direction of \(\overrightarrow{\mathrm{E}}\)
- B along the direction of \(\overrightarrow{\mathrm{B}}\)
- C parallel to the direction of \(\overrightarrow{\mathrm{E}} \times \overrightarrow{\mathrm{B}}\)
- D perpendicular to the direction of \(\overrightarrow{\mathrm{E}} \times \overrightarrow{\mathrm{B}}\)
