Light will not pass through a pair of Polaroid sheets when they are aligned perpendicularly. However, if a third Polaroid is sandwiched between the two with its alignment halfway between the alignments of the other two (that is, with its axis making a 45° angle with each of the other two alignment axes), some light does get through. Why?
Unpolarized light passes through two ideal Polaroid sheets. The axis of the first is vertical and the axis of the second is at 28.0° to the vertical. What fraction of the incident light is transmitted?
Unpolarized light passes through two polaroid filters that are oriented such that the angle between their polarization axes is 45o. What fraction of the incident light emerges from the system?
