A polarizer material is placed in front of an unpolarized light and the intensity of the light being transmitted is 2.00. A second polarizer material is placed in the front of the unpolarized light and has a referred direction rotated 30 o to that of the first material. What is the intensity of the light after it has passed through both polarizers?
Homework Answers
Intensity of light after passing the first polariser = 2.00
( Intensity of unpolarized light after transmission through a polariser reduces to half , independent of how polariser is placed. In this case intensity of unpolarized light must have been 4.00)
Intensity after being transmitted from second polariser is given by malus' law
= 2.00 × cos230°
I = 2.00 × (3/4)
= 1.50

An unpolarized light beam with intensity I0 is first passed through an ideal polarizer. At this instant, the light is polarized. We then pass that light through 3 more identical polarizers having parallel axes of transmission to each other. If the transmission axis of the final polarizer makes an angle of 35 ∘∘ with the electric field direction of the polarized light, what is the intensity of the emerging light? An unpolarized light beam with intensity I0 is first passed...
