Discuss the applications of polarised light in ... - SS2 Physics Optics - Wave Optics Question

Polarised light finds applications in various fields. In photography and cinematography, polarising filters are used to selectively block or enhance certain light waves, reducing glare and improving contrast and colour saturation. In optical microscopy, polarised light can reveal structural details and orientations of materials, aiding in the study of crystals, fibres, and biological specimens. Polarised sunglasses are commonly used to reduce glare and improve visibility, particularly for activities like driving or outdoor sports. Liquid crystal displays (LCDs) rely on polarised light to control the intensity and colour of pixels. Polarised light is also utilised in 3D movie projection, where different polarisations are used for each eye to achieve the perception of depth.
