Polarization after reflection of a mirror

Click For Summary
SUMMARY

The discussion centers on the behavior of circularly polarized light when reflected off a mirror positioned perpendicular to the optical axis. It is established that the two components of circularly polarized light experience a phase shift of π upon reflection, resulting in the light retaining its original polarization state. The use of wave plates is noted as a common method for altering polarization, contrasting with the role of mirrors in this context.

Homework Statement


If a light beam is circularly polarized and then bounced off a mirror perpendicular to the optical axis, what is the new polarization.

My thought is, because circularly polarized light has basically 2 components behaving like waves, each of them is going to experience a phase shift by pi, so then the light will have the same polarization as it had before.

Sounds right to me. Generally, we use http://en.wikipedia.org/wiki/Wave_plate" to alter the polarization of a wave, and not mirrors.
