Question

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. Only 82% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. No light passes through the second sheet. What angle does the transmission axis of the second sheet make with the vertical? (Let the +y-axis represent the upward vertical direction. Express your answer as a value between 0 and 180.)



_____________________ counter-clockwise from the +y-axis

Explanation / Answer

The light should be passes through vertical direction in 1st sheet

In vertical direction second sheet angle is

=arc tan(root i)

=arc tan(root 82)

=arc tan(9.05)

=83.69 degrees
