Questions
The magnetic field in the plane electromagnetic wave is given by
The expression for electric field will be
detailed solution
Correct option is D
Wave is propagating along positive X-axis; magnetic field is directed along Z-axis so electric field must be directed alongk∧×i∧=j∧ along Y-axis.Amplitude of electric fieldE0=B0c=2×10-7×3×108=60 V/mSimilar Questions
