Question

Malus' Law If two Polaroid filters are arraigned so that light passes first through one then the other, the first is called the polarizer and the second the analyzer. Malus' law states that the intensity of the light transmitted by the analyzer is proportional to the square of the cosine of the angle between the transmission axes of the polarizer and the analyzer. I_transmitted = I_incident COS^2 theta When Polaroid filters are placed so that minimum light passes through, the filters are said to be crossed. Use Malus' law to explain why crossed polarizers transmit a minimum of light.

Explanation / Answer

Itrnas = Iinci*cos^2theta

we know cos theta value decrease from 0 to 90

crossed polarizer have 90 degree angle

cos90 = 0

Itrnas = 0
