Select all the true answers. The rotation angle's sign matches that of the the cosine of the phase difference. The ellipticitv angle's sign matches that of the the sine of the phase difference. D If the magnitudes of ax and av are equal, the wave must be circularlv polarized D Linearlv-polarized waves are always exactlv inphase [:1 A wave's position along its direction of travel is not used to determine its polarization. [:1 All waves can be considered to be ellipticallv polarized; the linear and circular polarizations are just special cases that make the math less complicated. Two circularly-polarized waves travelling in the same space and in the same direction will not interfere with one another if their polarization "handedness" are opposite [i.e. LHC and RHC). {9 True 0 False Two linearly-polarized waves travelling the same direction will not interfere with one another if their polarization planes are orthogonal or perpendicular. 0 True (it) False
