    Light travels from one place to another as a wave. In some ways, it is like a wave on a lake. Light travels out in all directions from a source, much like a water wave travels away from a rock dropped into water. In a wave on a lake, the water moves up and down while the wave travels across the surface perpendicular2to the motion of the water. A li...

    To understand polarisation, picture a wave on a rope. If you make a series of up and down motions while holding onto a rope, a series of waves will move from your hand along the rope, transferring the motion down the rope. The rope moves up and down while the wave (and its energy) travels along the rope perpendicular to the motion of your hand. You...

    One method of polarisation is by the use of a special polarising filter or lens. To understand how a polarising lens works, let’s go back to our rope example. If you make vertical waves on a rope that go through a vertical slit, shown as in figure A in the image below, the waves would travel through the slit easily because the orientation of the sl...

    You can find examples of polarised light3in many places. When light is reflected off a surface at a steep angle, such as sunlight off the surface of water or an automobile windscreen, it becomes polarised. The glare from such reflections is greatly reduced by polarised lenses in sunglasses. The glasses worn by the audience in modern 3D films are po...

  4. Jun 27, 2019 · How do polarised lenses work? Sunlight scatters in all directions. But when it strikes flat surfaces, the light that is reflected by the surfaces tends to become polarised — meaning the reflected light beams travel in a more uniform (usually horizontal) direction.
