sun in their back sees this as the blue sky.
[3] a) Explain in 50 words and/or a figure what the orientation of
the electric and magnetic
fields are that enter the eye.
[3] b) Explain in 50 words and/or a figure why the scattered light
must have only this
polarization.
[4] c) The Poynting vector here is 2 W/m 2 . What is the amplitude
of the magnetic field?
