A uniform plane wave with electric field $E⃗(x)=A_y â_y e^{-j\frac{2πx}{3}} V/m$ is travelling in the air (relative permittivity, $ε_r=1$ and relative permeabi...

The magnetic field of a uniform plane wave in vacuum is given by H→(x,y,z,t)=(âx+2ây+bâz)cos(ωt+3x-y-z).The value of b is

A uniform plane wave traveling in free space and having the electric field E=(√2âx-âz)cos[6√3π×108t-2π(x+√2z)]V/m i...
