A plane electromagnetic wave of frequency 25 GHz is propagating in vacuum along the z - direction. At a particular point in space and time, the magnetic field is given by B  = 5 ×10 – 8 j ˆ T. The corr esponding electric field E  is (speed of light c = 3 × 10 8 ms – 1 )

1. 1.66 × 10 – 16 i ˆ V/m
2. 15 i ˆ V/m
3. – 1.66 × 10 – 16 i ˆ V/m
4. – 15 i ˆ V/m

Correct answer: 15 i ˆ V/m
