Polarized sunglasses work by allowing light waves vibrating in only one specific direction to pass through, based on what optical principle?

Explanation

Polarized sunglasses work based on the principle of polarization, using a special filter that allows light waves vibrating in only one specific direction, or plane, to pass through, while blocking light vibrating in other directions. This is particularly effective at reducing glare from surfaces like water or wet roads, since light reflecting off these horizontal surfaces tends to become strongly polarized in a specific horizontal direction that the sunglasses’ vertical polarizing filter can effectively block. Beyond sunglasses, the principle of polarization also has various other practical applications, including in certain types of camera filters and specific display screen technologies.
