Using Light: Polarized Light

The video explains how polarizing sunglasses help reduce glare by filtering light. It describes the mechanism of polarizing filters, which have tiny parallel slits that allow only certain planes of light to pass through, similar to Venetian blinds. This process results in polarized light, which vibrates along a single plane, effectively reducing glare and improving visibility for activities like skiing and fishing.
