Light from a strongly unpolarized light source is reflected at the Brewster angle towards a water surface. The reflected light is directed towards a polaroid filter and after the filter the irradiance is measured. When the filter's transmission axis is parallel to the E-field result vector, a maximum irradiance of 500 W / m² is measured.

a) What happens to the light in the Brewester angle? (Maximum half A4 page as explanation)

b) If the filter is turned 25 ° clockwise from the position where maximum irradiance is measured, what intensity is measured?

c) If a further polaroid filter is placed behind the first filter with the transmission axis parallel to the transmission axis of the first filter and then rotated 25 ° clockwise, what intensity is then measured? In the interrogation room where witnesses are to point out criminals, witnesses can see criminals but criminals cannot see witnesses.

d) Does this have to do with polarization? How does this work? (Maximum half A4 page as explanation)
