A linearly polarized electromagnetic wave given as \( \mathbf{E}=E_{o} \hat{\mathbf{i}} \cos (k z-\omega \mathrm{t}) \) is incident normally on a perfectly reflecting
\( \mathrm{P} \) infinite wall at \( z=a \). Assuming that the material of the wall is optically

W inactive, the reflected wave will be given as
(a) \( \mathbf{E}_{r}=-E_{o} \hat{\mathbf{i}} \cos (k Z-\omega \mathrm{t}) \).
(b) \( \mathbf{E}_{r}=E_{o} \hat{\mathbf{i}} \cos (k z+\omega \mathrm{t}) \).
(c) \( \mathbf{E}_{r}=-E_{o} \hat{\mathbf{i}} \cos (k z+\omega \mathrm{t}) \).
(d) \( \mathbf{E}_{r}=E_{o} \hat{\mathbf{i}} \sin (k z-\omega \mathrm{t}) \).
