Phase/Amplitude Resonance in Mirrors System

[semc]

Homework Statement

I am given a system of 4 mirrors, 1 of it partially transmit while the rest have 0 transmittance. I am ask to plot the ratio of the E-field of the wave exiting and entering the system and comment on whether this system exhibit resonance in phase or in amplitude. I just want to ask what does resonance in phase or in amplitude mean.

How are the mirrors arranged? This may determine the answer to your question.

I am not really looking for the answer to that question. I just don't know what does resonance in phase means. Anyway I tried drawing the system hope its not too bad. Thanks in advance!
