Two ideal linear sheet polarizers are arranged with their transmission axes at 10 degrees and 60 degrees with respect to vertical.
a) If a beam of linearly polarized light with its electric field at 40 degrees with respect to vertical enters the first polarizer, what fraction of its
irradiance will emerge from the second?
b) Replace the polarized beam with a beam of natural, randomly polarized light. Now calculate the fraction of the incident irradiance that emerges
from the second polarizer.
