A plane electromagnetic wave is travelling in air in +x direction. At a particular moment, its electric field \(\overrightarrow{{E}}\) is along +y direction. At that moment, the magnetic field \(\overrightarrow{{B}}\) is along:
- \(+z\) direction and in phase with \(\vec{E}\)
- \(-z\) direction and in phase with \(\vec{E}\)
- + z direction and out of phase with \(\overrightarrow{{E}}\)
- - z direction and out of phase with \(\overrightarrow{{E}}\)
Answer
(A) +z direction and in phase with E
