Electromagnetic Waves · EM waves

An electromagnetic wave travels in free space along the xx-direction. At a particular point in space and time, B⃗=2×10−7 ȷ^\vec{B} = 2\times10^{-7}\,\hat{\jmath} T is associated with this wave. The value of corresponding electric field E⃗\vec{E} at this point is V/m.
