Physics - Optics - Wave Optics - Polarization of light - Polarization of Light
A 5-step lesson. Step 1: 'Unpolarized light: The electric field oscillates in ALL directions perpendicular to the direction of travel (a mix of all planes). Polarized light: The electric field oscillates in only ONE plane.' Step 2: 'Polarization by filters: A polarizing filter (Polaroid) only transm
