Unpolarized light of intensity I0 = 750 W/m2 is incident upon two polarizers. After passing through both polarizers the intensity is I2 = 180 W/m2.
a) What is the intensity of the light after it passes through the first polarizer in W/m2?
b) Write an equation for the angle between the polarizers in terms of the initial (I0 ) and final (I2) intensities.
c) Find the angle between the polarizers in degrees.
