Question
Unpolarized light is sent through a polarizer with its polarization axis vertical. Then it
goes through a second polarizer with its polarization axis at an angle of 30° clockwise from the
11.
vertical. Finally, it goes through a third polarizer with its axis at an angle of 70° clockwise from
the vertical. The initial intensity of the light is I, = 1000",
a. What does it mean to say that light is polarized?
b. What is the intensity of the light after going through the first polarizer?
c. What is the intensity of the light after going through the third polarizer?
