Chapter 16, Problem 50P

The electric field of an electromagnetic wave is given by $E=\left(6.0\times {10}^{-3}V/m\right)\sin \left[2\pi \left(\frac{x}{18m}-\frac{t}{6.0\times {10}^{-8}s}\right)\right]\text{<mover accent="true"> <mi> j </mi> <mo> ^ </mo> </mover>}$

Write the equations for the associated magnetic field and Poynting vector.
