Unpolarized light passes through three polarizing filters. the first filter has its transmission axis parallel to the z direction, the second has its transmission axis at an angle of 30.0° from the z direction, and the third has its transmission axis at an angle of 60.0° from the z direction. if the light that emerges from the third filter has an intensity of 978.0 w/m2, what is the original intensity of the light? (assume both angles are measured in the same direction from the +z axis.)
