Answer 1

The scattered light that comes to me is vertically polarized while assuming that I'm facing south direction at a time when the sun is just setting.  

• In general, the sky is polarized tangential to a circle centred in the sun and maximum polarization is found at ninety degrees from it.  
• Therefore, with the sun close to the zenith the sky will be polarized horizontally along the entire horizon.  
• On the other hand, when the sun is setting West, the sky will be vertically polarized.
