Unpolarized light falls on two polarizer sheets whose axes are at right angles.
(a) What fraction of the incident light intensity is transmitted?
(b) What fraction is transmitted if a third polarizer is placed between the first two so that its axis makes a 56° angle with the axis of the first polarizer?
(c) What if the third polarizer is in front of the other two?
