Polarized light refers to light that has been filtered so that its vibrations occur in only one plane. This phenomenon is commonly associated with the interaction of electromagnetic waves with certain materials or structures, resulting in polarization. Polarized light is often used in various scientific fields, such as optics, spectroscopy, and microscopy, to study the properties of materials and to enhance image contrast. It can also be used in technological applications such as sunglasses, 3D movie projection, and liquid crystal displays. Research in polarized light focuses on understanding its behavior and properties, as well as developing new techniques and applications for its use in various fields.
