Question:

What are the uses for polarised light?

uses of polarisation, how is polarised light produced

Answer:

they are used to minimize the UV rays from entering in your eye glasses and window panes... polarise light is produce when an ordinary light passes through a membraine that acts like a filter and reduces the amount of light in parallel lines. you cannot see this since it is quite small with your naked eyes..
sunglasses, windows in air craft, holograms,
In a feeling, particular. A prism breaks gentle good right into a spectrum of diverse frequencies because of the reality those frequencies return and forth at diverse speeds in direction of the glass. A mass spectrometer breaks up a bypass of charged debris into spectrum of charge/mass ratios because of the reality debris with diverse charge/mass ratios are deflected otherwise by ability of an identical magnetic field.
The polarise Light has vertical and horizantal compenents.The reflected light from street or lake has damage the human eye vision.We have to use oplarized filter glases.
1.Polarization studies are made to investigate the transverse nature of light. 2. Polarization studies had suggested that saturn rings consists of ice crystals..So it can be used in astronomy. 3. size and shapes of certain viruses can b determined by the polarization of UV light scattered fro them.. 4. Information abt the structure of atoms and nucleus is obtained from Polarization studies of their emitted radiations in all parts of EM spectrum. 5. The liquid crystals which are used for the LCD on watches and calculators use polarized light to form letters and numbers. Polarized light is produced by passing light through a polarizer(eg:tourmaline crystal),Scattering of light or By reflection...
