What does it mean to be ‘cool from the sun’ not cool ’and to be free?
It means that the light emitted by the sun travels in all the given directions, i.e. on different polarized lights. And when it is transmitted over a distance, it has a slight separation, and is separated only when its measuring angle is equal to the angle of separation. Because sunlight is everywhere, it is said that light is not polarized. When uninterrupted light falls on an exposed surface with an incident angle equal to the angle of division of the earth or also called Brewster's angle, it is called polarized-polarized. When uncollected light is transmitted through a separating sheet, it is separated.
