What is a Polaroid? Write few uses of Polaroid's.
Asked by Topperlearning User | 13th Jun, 2014, 12:51: PM
A Polaroid is artificially prepared thin, large sheet of crystalline polarizing material capable of producing plane polarized light.
Uses of polaroids are:
- Used to produce and analyse polarised light as they are cheaper.
- To view three dimensional pictures.
- Used in motor car head lights and wind screen.
- Used in sunglasses to avoid glare of light
- In CD players, calculators, LCD,s

- Explain Polarisation by scattering? (4marks question ) So please provide accurate answer
- Prove that the polarising angle of incidence and the corresponding angle of refraction are complementary to each other.
- When sun is at 37° angle from horizon, then reflected light from water surface is totally polarised.Find refractive index of water
- Draw an intensity vs angle between the plans of transmission of polarizer and analyzer
- What is plane polarized light?
- State Brewster's law.
- Briefly explain polarisation by scattering?
- Two Polaroid’s are used to study polarization. If the analyzer is rotated through the angles of 450, 900 and 1800 in turn, how much the intensity of light coming out of the analyzer be affected by these angles of rotation, as compared to the initial intensity?
- How can one distinguish between an unpolarised light beam and a plane polarized light beam using a Polaroid?
