1. The problem statement, all variables and given/known data A polarized wave in the y axis, propagates in the z axis and is incident to a quarter-wave plate. Viewing the down from -z to z, the fast axis is 45deg below the x-axis. Determine the polarization of the beam immediately following the quart-wave plate. 2. Relevant equations Conceptual Question, I am not using equations.. 3. The attempt at a solution The wave must be circular but I cannot visualize how to determine whether it is left handed or right handed. I realize that if you curl your fingers in the direction that it rotates, the hand with the thumb pointing in the direction of propagation is the handedness but I can't visualize how the wave curls coming out.
