Transmitted light is partially polarized with intensity$\frac{{\mathrm{I}}_0}{2}$

Transmitted light is completely polarized with intensity less than$\frac{{\mathrm{I}}_0}{2}$

Reflected light is completely polarized with $\frac{{\mathrm{I}}_0}{2}$intensity less than$\frac{{\mathrm{I}}_0}{2}$

Reflected light is partially polarized with intensity $\frac{{\mathrm{I}}_0}{2}$
