'In many ways, the manufacturing strategy is helping us redefine and reinvent how we do business in General Motors,' said Scott Whybrew, GM's executive director of global manufacturing engineering.
When the phase shift is exactly Â±90Â°, then circular polarization is produced (fourth and fifth figures). Thus is circular polarization created in practice, starting with linearly polarized light and employing a quarter-wave plate to introduce such a phase shift.
Polarization is the aligning of vibrations in a transverse wave, usually by filtering out waves of other directions. Polarized light waves only travel vertically or horizontally -- when combined at right angles they block each other out and no net light can be detected.olarization is possible only when the direction of vibration is perpendicular to the direction of the wave travel, such is in light. In sound waves, the dire â¦ ction of vibration (compression) is the same direction as the direction of the travel of the sound wave, and therefore polarization is not possible.
