AP EAMCET · PHYSICS · Electromagnetic Waves
A plane electromagnetic wave of frequency \(25 \mathrm{MHz}\) travels in free space along the X-direction. At a particular point in space and time the electric field is \(\vec{E}=6.3 \hat{\mathrm{j} ~ V m}{ }^{-1}\). Then the magnetic field at that point is
- A \(2.1 \times 10^{-8} \hat{\mathrm{k} ~ T}\)
- B \(2.1 \times 10^8 \hat{\mathrm{k} \mathrm{T}}\)
- C \(2.1 \times 10^{-8} \hat{\mathrm{j} ~ T}\)
- D \(2.1 \times 10^8 \hat{\mathrm{j} ~ T}\)
