Suppose you have a polarized light source in your lab that has an intensity of 1364 W/m2, where the electric field oscillates in the z direction. The light travels toward a workbench where you can send it through either one of two polarizing filters.
(a) If the light passes through a filter with its transmission
axis at an angle of 45.0° from the z direction, what is
the intensity of the transmitted light?
=? W/m2
(b) If, instead, the light passes through a filter with its
transmission axis at an angle of 90.0° from the z
direction, what is the intensity of the transmitted light?
=? W/m2
