10. The magnetic field of a monochromatic, plane wave propagating in free space is given by $\vec{H}(\vec{r},t)=1.0(A/m)\cos (?t?y?z)\hat{x},\vec{E}(\vec{r},t)=E_m\cos (?t?y?z)\hat{c}$ (a) What is the force by this EM wave on a perfect, flat mirror of area $0.10{\mathrm{m}}^2$, lying on $y=1$ plane? (Hint: Em=cBm) (b) What if the mirror is painted with perfect absorber?
