A linearly polarized electromagnetic wave given as E=E_{0} \hat{i} \cos (k z-\omega t) is incident normally on a perfectly reflecting infinite wall at z=\mathrm{a}.
Assuming that the material of the wall is optically inactive, the reflected wave will be given as
a)E_{r}=-E_{0} \hat{i} \cos (k z-\omega t)
b)E_{r}=E_{0} \hat{i} \cos (k z+\omega t)
c)E_{r}=-E_{0} \hat{i} \cos (k z+\omega t)
d)E_{r}=E_{0} \hat{i} \sin (k z-\omega t)
