a) At sunset, sunlight is scattered by the atmosphere. A person looking straight up sees this as the blue sky. Explain in a few words what the orientation of the electric and magnetic fields are that enter the eye.
b) Explain in few words why the scattered light must have only this polarization.
c)If the Poynting vector for this light is 2 W/m 2 what is the amplitude of the magnetic field.
