Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is transverse to the direction of motion of the wave, so the oscillations can have different directions perpendicular to the wave direction. A simple example of a polarized transverse wave is vibrations traveling along a taut string; for example, in a musical instrument like a guitar string. Depending on how the string is p
