4. The electric field of a polarized light emerged from a polarizer can be expressed as E= Beei- Be Where B is the amplitude of the electric field. (d). The above electric field has passes through a quarter-wave plate (QWP). The fast axis (FA) of the QWP was located at the principal vertical axis, while the slow axis (SA) located along the principal horizontal axis. Determine the polarization state of the light that emerged from the QWP. (e). Given another identical QWP, choose the suitable orientation of the fast and slow axes so that the state of the electric field can be returned to E = Beli- Bele. (You need to provide explanation for your choice.)
