If the incident light is unpolarized, about what percentage (0 to 100) of the light intensity gets through a plane polarizer? If the incident light is unpolarized, what percentage (0 to 100) of the light intensity is is passed by a combination of the first polarizer and a second which has its polarization axis 45ˆ with respect to the first? If the indicent light is unpolarized, two polarizers aligned so that they are perpendicular will allow no light to pass through. If you insert a third polarizer in between them with its polarization axis at 45ˆ with respect to both of their polarization axes, what percentage (0 to 100) of the incident light will get through all three? (Hint: its not zero)
