Unpolarized light with an intensity of 655 w / m2 is incident on a polarizer with an unknown axis. the light then passes through a second polarizer with has an axis which makes an angle of 81.5° with the vertical. after the light passes through the second polarizer, its intensity has dropped to 163 w / m2. what angle does the first polarizer make with the vertical?

Explanation:
Polarizes axis can create two possible angles with the vertical.
first we have to find the intensity of first polarizer
which is given as
For a smaller angle for the first polarizer:
According to Malus Law
taking square root on both sides
For a larger angle for the first polarizer:
According to Malus Law
taking square root on both sides
