A polarizing filter is an optical device that selectively allows light waves of a specific polarization to pass through while blocking other orientations of light. This tool is crucial in various applications such as photography and reducing glare from reflective surfaces. It works on the principle of polarization, which refers to the orientation of light waves, and is also significant when discussing phenomena like Brewster's angle, where the polarization of light plays a key role in understanding reflection and transmission.
congrats on reading the definition of Polarizing filter. now let's actually learn it.
