Explain the concept of polarisation of light Ho... - SS1 Physics Wave Optics Question

Polarisation of light refers to the alignment of light waves along a specific orientation, typically in a single plane. Unpolarised light consists of light waves vibrating in random directions. When unpolarised light passes through a polarising filter, it becomes polarised, with only the light waves vibrating in a specific direction allowed to pass through. This results in a reduction in the intensity of the light. Examples of polarised light include light reflected off a smooth surface or light passing through certain materials, such as polarising sunglasses or LCD screens.
