Question

Unpolarized light of equal intensity is incident on four pairs of polarizing filters. Rank in order, from largest to smallest, the intensities Ia to Idtransmitted through the second polarizer of each pair.

Explanation / Answer

Ia = Id > Ib = Ic(when the angle of rotation for the two polarizers is same i.e 30degreesbut in opposite direction ) Ib = Ic > Ia = Id(when the angle of rotation for one polarizer(anti clockwise) (1st one)60 degrees and the other is 30 degrees but opposite direction Ib = Ic > Ia > Id(first one is 30 degrees anti clockwise other 60 degrees clockwise) Id > Ia > Ib > Ic(both anticlockwise 30 degrees) Id > Ia > Ib = Ic
