At a beach the light is generally partially polarized due to reflections off sand and water. At a particular beach on a particular day near sundown, the horizontal component of the electric field vector is 2.3 times the vertical component.A standing sunbather puts on polarizing sunglasses; the glasses eliminate the horizontal field component. (a) What fraction of the light intensity received before the glasses were put on now reaches the sunbather’s eyes? (b) The sunbather, still wearing the glasses, lies on his side. What fraction of the light intensity received before the glasses were put on now reaches his eyes?

Question
At a beach the light is generally partially polarized
due to reflections off sand and water. At a particular beach on
a particular day near sundown, the horizontal component of the
electric field vector is 2.3 times the vertical component.A standing
sunbather puts on polarizing sunglasses; the glasses eliminate
the horizontal field component. (a) What fraction of the light intensity
received before the glasses were put on now reaches the
sunbather’s eyes? (b) The sunbather, still wearing the glasses, lies
on his side. What fraction of the light intensity received before
the glasses were put on now reaches his eyes?
