CBSE Class 12 science: Polarisation Videos | Concepts based on polarisation

• Please refer to the uploaded image for the doubt
  
• 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?
• What is a Polaroid? Write few uses of Polaroid's.
• 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?
