how can i go about calculating the relative phase of reflected / transmitted fields for normally incident plane waves?

for example, i know how to calculate the relative amplitude of the reflected field from the reflection coefficient:

[tex]\Gamma[/tex] = E

_{r}/E

_{i}= ([tex]\eta[/tex]

_{2}-[tex]\eta[/tex]

_{1})/([tex]\eta[/tex]

_{2}+[tex]\eta[/tex]

_{1})

however, what if i want to calculate the relative phase?
