Grade 12 physics problems :(
One question:
Because of absorption, a Polaroid will actually transmit 40% of nonpolarized light incident on it. Two such Polaroids with their axes aligned will transmit
a. 16%.
b. 24%.
c. 30%.
d. 32%.
e. 40%.
The answer is 32% and I have no cue why. My textbook doesn't say anything and since I am taking a conceptual physics course, I have no formulas to work with. Does anyone know why this is the answer?
Thanks,
LA
