- Unpolarized light is incident on two polarizers X and Y. The transmission axis of X is vertical and that of Y is horizontal. [Figure shows unpolarized light incident on vertical polarizer X and horizontal polarizer Y.]
Polarizer Z can be placed
I. before polarizer X.
II. between polarizer X and Y.
III. after polarizer Y.
The transmission axis of Z makes an angle of 45° with those of X and Y.
At which positions for Z will no light be transmitted?
two polarizers X (vertical) and Y (horizontal)
